    This study concerns development of a non-destructive method to control conduction and magnetism of molecular solids such as single crystals of charge-transfer complexes. The method is named "optical doping", where appropriate irradiation is utilized under ambient conditions. Owing to this feature, it can be applied to a wide range of substances while measuring the properties during the control. In addition, the method adds unique conduction and magnetic properties to common insulators. Unlike other doping methods, optical doping only affects the properties and/or structures of the irradiated part of a sample while leaving the rest of the sample unchanged. There are two patterns in the optical doping. Irreversible optical doping produces junction-structures on the single molecular crystals, which exhibit characteristic behavior of semiconductor devices such as diodes and varistors. Reversible optical doping produces "giant photoconductors" and "photomagnetic conductors" by realizing unprecedented metallic photoconduction. In the latter case, localized spins are also excited to produce a Kondo system, where carriers and localized spins interact with each other. Not only the control of conduction and magnetism, the optical doping has realized the observation of physical properties in molecular crystals hardly observed under any thermodynamic condition.

    [Cu(dmit)(2)](2-) formally consists of a magnetic Cu2+ ion (S = 1/2) and closed-shell pi-conjugated dmit(2-) ligands. However, it has been determined by electron spin resonance and molecular orbital calculations that the majority (91-100%) of the spin delocalizes over the ligands in the ground state, while the spin significantly (40-90%) localizes on Cu under UV irradiation. Considering the results of X-ray structural analyses under UV irradiation, the spin distribution varies depending on the wavelengths irradiated and retaining the square-planar coordination geometries.

    beta-DiCC[Ni(dmit)(2)] (dmit: 1,3-dithiole-2-thione-4,5-dithiolato and DiCC: 3,3'-dihexyloxacarbocyanine) is a charge-transfer salt with redox activity. When voltages are applied, it brings about a reversible, hysteretic, solid-state-electrolytic reaction exhibiting a capacitor-like electric response. Based on the electron spin resonance spectra, the resistivity behavior, and the tight-binding band calculation, it is indicated that one can finely and reversibly control the redox equilibrium between DiCC(+) and [Ni(dmit)(2)](-) molecules by applying voltages.

    It is well-known that cooperative properties such as magnetic ordering can depend on the samples' dimensions (Ds) in a qualitative way. However, there have been no samples with well-defined non-integer Ds. The dimension of a given sample has been always discussed on the anisotropy of the electronic/crystal/magnetic structures, which has no definition suitable for quantitative discussion on dimensions vs. properties. On the other hand a particular type of porous samples, i.e. fractal bodies, can have well-defined non-integer Ds dependent exclusively on the geometrical feature of structures, and physical properties of such materials remains unexplored. This paper reports on magnetic ordering in samples covering 2.5 <= D <= 3, in addition to a way of precise control of the fractal dimensions of given samples simply by wax (alkylketene dimer). The results show that the magnetic ordering temperatures, i.e. Neel temperatures (T(N)s), of CoO depend on D, and rapidly enhance immediately below D = 3. This means that one can control or enhance the critical temperature simply by tuning D with keeping the remaining magnetic properties unchanged.

    An organic insulating crystal reversibly becomes a magnetic conductor under UV irradiation. The rapid and qualitative change in the physical properties is wavelength selective and explained by charge transfer between donor and photochemically active acceptor molecules. The photochemical redox reaction in the crystal produces a partially filled band and localized spins simultaneously.

    UV irradiation reversibly switches a new insulating and nonmagnetic molecular crystal, BPY[Ni(dmit)(2)](2) (BPY = N,N'-ethylene-2,2'-bipyridinium; Ni(dmit)(2) = bis(1,3-dithiole-2-thione-4,5-dithiolato)nickelate(III)), into a magnetic conductor. This is possible because the bipyridyl derivative cations (BPY2+) trigger a photochemical redox reaction in the crystal to produce a change of similar to 10% in the filling of the Ni(dmit)(2) valence band, leaving localized spins on the BPY themselves. In the dark, almost all of the BPY molecules are closed shell cations, and most of the Ni(dmit)(2). radical anions form spin singlet pairs; thus, this material is a diamagnetic semiconductor. Under UV irradiation, a photocurrent is observed, which enhances the conductivity by 1 order of magnitude Electron-spin resonance. measurements indicate that the 'UV:. irradiation reversibly generates. carriers and localized spins on the Ni(dmit)(2). and the BPY, respectively: This high photoconductivity can be explained by charge transfer (CT) transitions between Ni(dmit)(2) and BPY in the UV region. In other words, the photoconduction and "photomagnetism" can be described as reversible optical control of the electronic states between an ionic salt (BPY2+/[Ni(dmit)(2)](-), nonmagnetic insulator) and a CT complex (BPY2(1-delta)+/[Ni(dmit)(2)]((1-delta)-) (delta approximate to 0.1), magnetic conductor) in the solid state.

    The electrical conductivity of the organic Mott insulator ET-F(2)TCNQ (ET = bis(ethylenedithio) tetrathiafulvalene, F(2)TCNQ = 2,5-difluoro-7,7,8,8-tetracyanoquinodimethane) crystal was found to be enhanced by conjugation with a tetrathiafulvalene (TTF) single crystal on its surface; surface sheet resistance decreased from 5 x 10(5) to 2 x 10(3) Omega/sq. The mechanism of this decrement was investigated through optical and atomic force microscopy measurements at the interface. When TTF was conjugated to the ET-F(2)TCNQ crystal, electron injection from TTF and complex formation between TTF and F(2)TCNQ occurred. Neutral ET molecules were consequently generated at the interface, and this charge doping broke the Mott insulating state. (C) 2012 American Institute of Physics.

    Electrolysis of Na and K salts of the anion dicyano(phthalocyaninato) cobalt(III) (Co(Pc)(CN)(2)) in ethanol yields one-dimensional partially oxidized salts of A[Co(Pc)(CN)(2)](2)center dot 4(EtOH) (A = Na and K). The cationic component is the supramolecular cation [A(EtOH)(4)](+), which forms hydrogen bonds with the CN ligands of the Co(Pc)(CN)(2) units. The crystal shows metallic conductivity, in contrast to the thermally activated conductivity observed in the isomorphous tetraphenylphosphonium (TPP) salt of TPP[Co(Pc)(CN)(2)](2). Since the pi-pi interactions in these isomorphous crystals are nearly the same, the distinctive behavior of the Na and K salts may be attributed to the difference in the degree of charge disproportionation in these crystals.

    Electrolysis of ET in a mixed solvent of methanol/CHCl3 with bromide yielded (ET)(3)(Br-3)(5), in which an unusually high formal charge of ET5/3+ is achieved. ET forms a two-dimensional conducting sheet incorporating Br-3(-). Despite the high formal charge of the ET cations, the strong electrostatic attractions between the ET cations and Br-3(-) support aggregation of the ET cations, allowing sufficient pi-pi overlap for delocalization of the pi-electrons. The crystal shows stable metallic behavior down to low temperatures, being consistent with the metallic band structure with two-dimensional Fermi surfaces and Pauli-like paramagnetism down to low temperatures. The lack of any indication of instability in the metallic phase due to correlation effects is considered to result from an ionic-crystal-like structure, in which the lattice is more resistant toward lattice deformation and/or shrinkage than in typical partially oxidized salts with low formal charges.

    Understanding how electrons behave, i.e., carrier dynamics, in superconductors is indispensable for understanding the mechanism of superconductivity. Recently we have reported the carrier dynamics of kappa- and lambda-(BETS)(2)MCl4 (BETS = bis(ethylenedithio)tetraselenafulvalene, M = Ga, Fe) based on ultrafast spectroscopy, but the interpretation of the results remains an open question. In this paper we interpreted the results with the aid of newly measured magnetic susceptibility, X-ray single crystal structural analysis, and band calculation. Observation of coherent phonons only in the lambda-type salts indicated that e-ph interaction should be characteristically strong in the A-type salts. By comparison of the observed carrier dynamics with a two-temperature model, the temperature-dependence of carrier dynamics is consistently explained by the different strengths of the e-ph interaction between the lambda- and the kappa-type salts. The difference in strength of the e-ph interactions is related to their crystal structures. In conclusion, their carrier dynamics is consistently interpreted and classified by their crystal structures.

    The interface between tetrathiafulvalene (TTF) and 7,7,8,8-tetracyanoquinodimethane (TCNQ) crystals was prepared by treating a TCNQ single crystal surface with TTF powder. Optical measurements and atomic force microscopy (AFM) observation of the interface indicated that not only are TTF-TCNQ nanocrystals formed at the interface, but also direct charge injection from TTF powder to the TCNQ single crystal surface may be responsible for the high conductivity of the interface.

    The charge distribution in the surface BEDT-TTF layer of the alpha-(BEDT-TTF)(2)I-3 crystal with the charge disproportionation state at room temperature was studied in detail by a scanning tunneling microscope (STM), where BEDT-TTF (abbreviated as ET) is bis(ethylenedithio) tetrathiafulvalene. The obtained molecular charge distribution in the surface ET layer suggests that the electronic states of the surface ET layer at room temperature is the charge-ordered state, stable below 135K in bulk crystals, rather than the charge disproportionation state above 135 K. The most probable mechanism underlying this remarkable finding is the particular freedom to the surface ET layer. The missing of the I-3 layer partially removes the structural constraint of the steric interaction between the thermally vibrating ethylene groups and the neighboring two I-3 layers. This mechanism would have something in common with the layered ET complexes.

    Time-resolved photoresponses in resistance have been measured following the nanosecond laser pulse excitation for the quasi-two-dimensional organic superconductors of hydrogenated and deuterated beta-(BEDT-TTF)(2)I-3 [BEDT-TTF = bis-(ethylenedithio)tetrathiafulvalene], which show two different superconducting states with high-T-c and low-T-c at temperatures near the critical temperatures. A transient increase of the resistance is induced by photoirradiation at all the temperatures, but a marked temperature dependence of the decay time is observed at temperatures close to the high-T-c phase transition temperature; the decay rate becomes faster and then becomes constant in both compounds, as the temperature decreases across the high-T-c phase transition temperature. The temperature dependence of the photoresponse intensity is different from the one expected from the bolometric effects, indicating the presence of the nonbolometric photoresponse. A possible mechanism explaining the photoresponse of the conductivity is discussed, based on the isotope effect on the photoresponse. A comparison is also made between beta-(BEDT-TTF)(2)I-3 and kappa-(BEDT-TTF)(2)Cu[N(CN)(2)]Br for the transient photoresponse in resistance at temperatures across the metal-superconductor phase transition temperature.

    We have recently found that organic conductors Ag(DR)(2) (DR = 2,5-disubsituted-N,N'-dicyanoquinone amine; substituent (R) = CH(3), Cl, Br, I) irreversibly vary their electrical and magnetic properties by UV irradiation. By selecting the irradiation conditions (wavelengths, temperature, atmosphere, duration), one can accurately control the physical properties from metallic to insulating behavior while retaining their crystal structures. In order to clarify the mechanism of the conductivity change in the case of R = Cl, Br, and I, structure analysis of the irradiated crystals has been carried out. Transmittance electron microscopy and X-ray single crystal structure analysis clarified that the Ag(DCl)(2) crystals after 72 h irradiation (375 nm) contained single crystals of nearly three-dimensionally ordered AgCl (0.9 in mole fraction) with varying dimensions (similar to 1-50 nm). Owing to such a unique hybrid crystal structure, a highly nonlinear current-voltage characteristic unlike any existing electronic devices is observed on irradiated single Ag(DCl)(2) crystals.

    The structural and electrical properties of a metal-halide cubic perovskite, CH3NH3SnI3, have been examined. The band structure, obtained using first-principles calculation, reveals a well-defined band gap at the Fermi level. However, the temperature dependence of the single-crystal electrical conductivity shows metallic behavior down to low temperatures. The temperature dependence of the thermoelectric power is also metallic over the whole temperature range, and the large positive value indicates that charge transport occurs with a low concentration of hole carriers. The metallic properties of this as-grown crystal are thus suggested to result from spontaneous hole-doping in the crystallization process, rather than the semi-metal electronic structure. The present study shows that artificial hole doping indeed enhances the conductivity.

    The partially-oxidized TPP[M(Pc)L-2](2) molecular conductors exhibit variable electronic and magnetic transport bulk materials properties due to central metal and axial ligand molecular modifications. The controllable electrical conductivity and giant negative magnetoresistance can be mainly attributable to the varying ligand field energy and physical bulkiness of the axial ligands which cause modulation in the intra-molecular pi-d (Pc-M) and inter-molecular pi-pi (Pc-Pc) interactions in the TPP[M(Pc)L-2](2) system, respectively. Characterization of the electronic conduction band utilizing one-dimensional (1-D) tight-binding approximation from infrared reflectance and thermoelectric power profile reveal consistent band widths of 0.43 eV-0.62 eV for the Co series (L = Br < Cl < CN) and 0.44-0.56 eV for the Fe series (L = Br < Cl < CN). The fixed band width suggests that stable electron conduction bands (transport pathway) can be constructed which can withstand the molecular pi-d interaction modifications that severely alter the bulk electronic and magnetic materials properties of the TPP[M(Pc)L-2](2) molecular conductors.

    Unprecedented memory effect of photoinduced switching of the electrical conductivity in alpha-(BEDT-TTF)(2)I-3 controlled by the temporal width of square-wave pulsed voltages was reported where BEDT-TTF represents bis(ethylenedithio)tetrathiafulvalene [9] [limori et al 2009] Here further study has been done in order to examine whether the memory effect can be controlled by changing the height of the pulsed voltage Threshold values in the voltage height for the occurrence of the memory effect are characterized as a function of the width of pulsed voltages The relation between the threshold height and the pulse width can be altered by a load resistance connected to the sample in series in a measurement circuit It is also argued that time profiles of current observed in response to the application of pulsed voltages are inconsistent with a scenario in which the memory effect is ascribed to a temperature rise of the sample caused by photoirradiation and the successive application of pulsed voltages i e the memory effect is not a thermal effect (C) 2009 Elsevier B V All rights reserved

    Photoinduced change in the electrical conductivity of a single crystal of kappa-(BEDT-TTF)(2)Cu[N(CN)(2)]Br (kappa-Br) has been examined at various temperatures in the vicinity of the metal superconductor phase-transition temperature (T-c) with a nanosecond visible laser pulse. The transient change of the electric potential difference was measured following photoirradiation, and the time profile of the electrical conductivity was obtained in the current-biased sample. Upon photoirradiation, the bulk resistance increases at all the temperatures under the present study. However, the decay profile shows a marked temperature dependence, and a prolongation of the decay time is observed at temperatures just below T-c. The relaxation times below and above T-c are different from each other, and unconventional asymmetry of the critical slowing down about T-c is found. The presence of a nonthermal (nonbolometric) photoirradiation effect is confirmed in the superconducting phase of kappa-Br based on the analysis of the temperature dependence of the photoresponse in the conductivity.

    In order to compare the carrier dynamics and reveal the origin of differences in their electrical behaviour, time-resolved reflectivity changes were measured on single crystals of the title compounds. The observed relaxation behaviour explained well their electrical behaviour, and indicated that different conduction mechanisms dominated kappa-and lambda-type BETS salts, irrespective of local spins, at about 8-100 K; the electrical behaviour of the kappa-type salts is governed by relaxation times of carriers and/or density of states at the Fermi levels, while that of the lambda-type salts is dominated by the latter.

    A peak appearing at the L-2,L-3 X-ray absorption edge often provides the number of empty d states of the X-ray absorbing atoms. Ag+ compounds have a d(10) state (no d empty states) but Show a small peak at the edge. In this research, we systematically studied the edge peak of Ag+ compounds to Understand its origin oil the basis of the molecular Orbital picture and to obtain a relation of the edge peak intensity to chemical and physical quantities. The edge peak call be formally assigned to the transition from 2p to 5s enhanced by the s-d hybridization. The peak intensity has a negative correlation with I coordination charge but has a positive correlation with the strength of the covalent bond, which is in the reverse order to the other d(n) (n < 10) elements.

    Electrochemical oxidation of [M(III)(Pc)(CN)(2)](-) (M = Co and Fe, Pc = phthalocyaninato) and peri-xanthenoxanthene (PXX) in acetonitrile yields partially oxidized salts of [PXX](2)[M(Pc)(CN)(2)]center dot CH(3)CN. In the crystal, the Pc ring is formally oxidized by 0.5 e and forms a two-dimensional double-sheet layer. These crystals show semiconducting behavior with small activation energy under ambient pressure, but show metallic behavior under high pressures. When M - Co, the metallic behavior is maintained down to 5 K. On the other hand, in the pi-d system with M = Fe, the metallic behavior is disrupted by a steep increase in the resistivity at low temperatures. In this high resistivity state, negative differential resistance appears in the measurements of current-voltage characteristics, suggesting the development of charge disproportionation due to the pi-d interaction. The magnetic susceptibility for M = Fe reflects anisotropic molecular magnetism of the Fe(Pc)(CN)(2) unit, and shows an anomaly due to antiferromagnetic interaction between the Fe d-spins. The increase in the resistivity at low temperature under high pressures is suppressed by the application of a magnetic field. The magnitude of the negative magnetoresistance effect is extremely large; -99.8% was recorded at a field of 15 T at 3 K under 12 kbar.

    The Ag(DMe-DCNQI)(2) (DMe-DCNQI = 2,5-dimethyl-N,N'-dicyanoquinonediimine, or DM) charge-transfer salt is a promising material for production by photolithography as it displays a unique photoinduced change in conduction. Photoproducts (beta 1 and gamma) of Ag(DM)(2) were investigated using the X-ray absorption fine structure (XAFS) technique in order to understand the origin of their conduction properties. In contrast to the metallic conduction exhibited by a pristine sample (alpha), beta 1 is a semiconductor, whereas gamma is an insulator, even though the original Ag(DM)(2) composition is maintained in both the beta 1 and the gamma forms. A redox mechanism has been postulated to explain the photoinduced change in conduction. However, measurement of the Ag L-3-edge XANES (X-ray absorption near-edge structure) did not provide any evidence of electron transfer from the DM radical anion to the Ag cation in the beta 1 and gamma products. Ag K-edge extended X-ray absorption fine structure (EXAFS) data demonstrated that beta 1 is a mixture of the original pristine alpha phase and a newly found alpha' phase, which has a shorter bond distance between the Ag cations and the N atoms of DM molecules. The conduction electrons remain in the DM column of alpha and alpha', but the domain boundaries between alpha and alpha' present an activation barrier for the conduction electrons to cross these boundaries, which provides a rationale for the semiconductive behavior of beta 1. The Ag K-edge EXAFS results showed that the gamma photoproduct has a different local structure from alpha, with a shorter distance and smaller coordination number of the Ag-N bond. The DM radical anions in the gamma compound form covalent bonds between themselves, resulting in a loss of the columnar structure. The complex local structure around Ag cations explains the insulating behavior of the gamma compound.

    Electrochemical oxidation of bis(ethylenedithio)terathiafulvalene (ET) with mellitic acid and pyridine in methanol produces a partially oxidized salt of [ET](3)[C(6)(COO)(6)H(4)(2-)](2)[C(5)H(5)NH(+)](2)center dot CH(3)OH center dot 2H(2)O (1). In the crystal of 1, mellitate anions form a two-dimensional hydrogen-bonding double-sheet layer with pyridinium, methanol, and water. ET molecules are packed between the layers, forming a two-dimensional conducting sheet. The ET arrangement in the sheet resembles that in alpha-ET(2)I(3), which has it metal-to-insulator transition. The transition into insulating states is completely suppressed in 1 due to the close packing of ET molecules in the supramolecular mellitate network.

    The charge transport properties of a partially oxidized salt composed of Co(Pc)(CN)(2) units with a typical one-dimensional electronic system have been suggested to be determined by charge disproportionation. The current-voltage (I-V) characteristics show nonlinear behavior at low temperature, which is suppressed by applying pressure. The observed nonlinearity is considered to result from the electric-field-induced delocalization of carriers in the charge disproportionation state. In the isomorphous magnetic Fe(Pc)(CN)(2) system, the nonlinear behavior is observed at higher temperatures, suggesting that charge disproportionation is more developed in a system with local moments. The threshold voltage of negative differential resistance decreases when an external magnetic field is applied, confirming that the localization of charge carriers is released by magnetic field application.

    Electrical conductivity switching is induced by photoirradiation in single crystals of alpha-(BEDT-TTF)(2)I(3) below 135 K. Photoirradiated crystals show differential negative resistance (DNR), and bistability is observed in the electrical conductivity as a function of applied voltage. The threshold in voltage, which induces the DNR, increases as the temperature decreases. A hysteresis loop appears in the current versus light intensity characteristic curve, and the feature of the hysteresis loop depends on the pulse width of the applied voltage. The switching to a high conductivity state is initially triggered by the laser light irradiation. The conductivity switching can be repeatedly recovered only by applying the pulsed voltages without further photoirradiation even after the cur-rent was reduced to zero, indicating a memory effect in the photoinduced conductivity switching. When pulsed voltages having smaller width and/or height than the corresponding threshold values are applied to the crystal, the field-induced recovery to the high-conductivity state due to the memory effect fades out. The thresholds in width and height of the pulsed voltage for the memory effect can be controlled by the photoirradiation light intensity. These results show that the electrical conductivity can be controlled by the width and height of the pulsed voltage as well as the light intensity without a change in temperature or pressure.

    A series of one-dimensional conductors, TPP[Fe-III(Pc)L-2](2) with L CN, Cl, and Br, have been prepared. These compounds show giant negative magnetoresistance due to the interaction between conduction pi-electrons and localized Fe-centered d-spins, but the magnitude is found to vary based on the axial ligand, suggesting that the strength of the pi-d interactions is sensitively influenced by the axial substituent. The magnetic susceptibility also shows the difference in the magnetic interactions by the axial substituent. The ab initio calculation of the isolated molecules has revealed that the Jahn-Teller effect in this system induces splitting of d(xz) and d(yz) orbitals, and that the energy shift of the d-orbital accommodating an unpaired electron is varied by the axial substituent. The axial-ligand dependence of the intramolecular pi-d interaction is found to correlate with the magnitude of the magnetoresistance.

    Transient photoresponses of the electrical conductivity in single crystals of an organic conductor alpha-(BEDT-TTF)(2)I-3 are studied in the charge-ordered insulating phase. Electrical conductivity switching is observed in the presence of pulsed voltages and synchronous irradiation of nanosecond laser pulse. Current in the photoirradiated crystal as a function of applied voltages shows a bistability in a certain range of voltage. For the initial triggering of the conductivity switching, not only pulsed voltages but also photoirradiation is necessary. A high conductivity state produced by the switching can be repeatedly recovered by applying the pulsed voltages without further photoirradiation even after the current has been reduced to zero. This observation indicates a memory effect of the photoinduced conductivity switching. The appearance of the memory effect depends on the temporal width of the pulsed voltages, which are applied at a rate of approximately 8 Hz. In the measurement using short pulse widths, the memory effect is not observed. This controllability of the memory effect with the pulse width is related to the bistability of the current with respect to the photoirradiation intensity. The shape of the hysteresis loop appearing in the current versus photoirradiation intensity curve can be varied by changing the pulse width.

    The K-type organic superconductors have unique physical properties, many of which are yet to be understood. Most of their physical properties are closely related to carrier dynamics, which can be directly observed by ultrafast optical measurements in their nonequilibrium states. Time-resolved temperature-dependent reflectivity changes were measured on single crystals of an isostructural pair of organic charge transfer salts kappa-(ET)(2)Cu[N(CN)(2)]X, which are ambient- (X = Br) or high-pressure (X = Cl) superconductors. The latter compound in its ground state is a Mott insulator under ambient pressure. The obtained temperature dependences of relaxation times for both salts indicated the existence of an intermediate electronic state between those of metals and insulators at all measurement temperatures. Such an unusual electronic state coexisted with the superconducting and Mott insulating states in X = Br and X = Cl, respectively. In addition, the results for X = Br revealed the formation of a temperature-dependent well-defined gap in the superconducting transition, while those for X = Cl suggested that the Mott transition in this salt does not depend on electron-phonon interactions, consistent with the theory that the Mott transition should originate from electron correlation.

Ag valence state in each photochemical product was determined by Ag L-3-edge XANES. The XANES result requires the correction of the redox mechanism to explain the photoinduced conductivity change of Ag(DM)(2) photoproducts.

    A charge-transfer complex of 2,5-dimethyl-N,N'-dicyanoquinonediimine (DM) with silver (crystalline Ag(DM)(2), defined as a) is irreversibly transformed by UV-vis illumination. Depending on the illumination conditions, three new types of solids (defined as gamma, delta, and epsilon) with different structural and physical properties are obtained and examined by a variety of analytical techniques, including solid-state, high-resolution, cross-polarization magic angle spinning (CP-MAS) (CNMR)-C-13, elemental analysis (EA), mass spectrometry (MS), X-ray absorption fine structure (XAFS), and powder X-ray diffraction (XRD). The CP-MAS, EA, MS, and XAFS results indicate that compound gamma is a glass state of Ag(DM)(2). The transformation from crystalline (a) to amorphous (gamma) solid Ag(DM)(2) is an irreversible exothermic glass transition (glass-transition temperature 155.2 degrees C; Delta H=-1.26.8 kJ mol(-1)), which implies that the glass form is thermodynamically more stable than the crystalline form. Compound delta (Ag(DM)(1.5)) consists of silver nanoparticles (diameter (7 +/- 2) nm) dispersed in a glassy matrix of neutral DM molecules, The =N-CN-Ag coordination bonds of the a form are not maintained in the delta form. Decomposition of a by intense illumination results in a white solid (epsilon), identified as being composed of silver nanoparticles (diameter (60 +/- 10) nm). Physical and spectroscopic (XAFS) measurements, together with XRD analysis, indicate that the silver nanoparticles in both delta and epsilon are crystalline with lattice parameters similar to bulk silver; however, the magnetic susceptibilities differ from bulk silver.

The transient photocurrent at 115 K shows a remarkable persistence at the metallic conductivity and a nonlinear dependence on the light intensity, probably originating from the photoinduced M-I phase conversion in the presence of electric fields.

    We report that the photoinduced high conductivity (HC) state in the organic charge-transfer salt alpha-(BEDT-TTF)(2)I-3, which is initially triggered by a pulsed voltage and synchronous photoirradiation, can be repeatedly recovered without further photoirradiation by application of a pulsed voltage even after the current has been reduced to zero. The recovery to the HC state can be controlled by adjusting the pulse width and/or amplitude. By proper selection of pulsed voltage parameters, the switching can be made reversible or irreversible. Hysteresis loops in the current-voltage and current-irradiation intensity curves of the circuit demonstrate a memory effect with potential application in unconventional photoswitching operations. The characteristic of the hysteresis loop and current bistability can be flexibly varied by changing the width of the applied pulsed voltage.

    Pyromellitate is known to form hydrogen-bonding anionic networks when the number of deprotonation from pyromellitic acid is one or two. This unique anion has been utilized for the construction of the pi-radical cationic salts of the tetrathiafulvalene (TTF) derivatives. In the crystals of three kinds of the TTF salts and the tetramethyltetraselenafulvalene salt, pyromellitate was found to form two-dimensional sheets. The anions in the two TTF salts were connected by rhombic-type inter-anionic connection, which is a typical inter-anionic connection pattern for pyromellitate. The TTF derivatives were all in a 7 pi-radical mono-cationic state and dimerized in a space dictated by the anionic networks. The extra space in the crystals was filled with crystal solvents. On the other hand, in the crystals of the ethylenedithia-tetrathiafulvalene salts, pyromellitate formed only intra-molecular hydrogen bonds. The anion was thus isolated in these crystals.

    We investigated the ground state of a highly one-dimensional conductor, TPP[Co(Pc)(CN)(2)](2) (TPP tetraphenylphosphonium and Pc = phthalocyanine), by the measurement of the X-ray diffraction, electron spin resonance, nuclear quadrupole resonance, and magnetoresistance. An increase of the magnetic fluctuations was observed below 20 K, where no structural deformation was detected. In the Co-59 nuclear quadrupole resonance, we found an asymmetric broadening of the spectra owing to the intrinsic inhomogeneity of the molecular charge. We propose that the ground state is characterized by a weak charge disproportionation with antiferromagnetic fluctuations due to the high one dimensionality. A large magnetoresistance was observed under a high magnetic field. Spin effects are dominant at low fields. The anisotropic magnetoresistance suggests a change in the ground-state nature above 10 T.

    The C-4h isomer of the 1,2- Nc ( 1,2- naphthalocyaninato) ligand has been efficiently isolated as a hydrated magnesium complex by the fractional crystallization from the benzene/ acetone solution after treating the crude mixture of the four isomers ( C-4h, C-s, C-2v, D-2h) with benzene. The C-4h symmetry has been confirmed by X- ray structure analysis. The central metal ion has been demetalated and subsequently converted to the Li-2 complex followed by conversion to the cobalt( II) complex. Electrochemical oxidation of the Co-III( 1,2- Nc)( CN)(2) anion prepared from the cobalt( II) complex with TPP ( tetraphenylphosphonium) has yielded a partially oxidized salt, TPP[ Co-III( 1,2- Nc- C (4h))( CN) (2)] (2). The crystal comprises slipped stacked Co-III( 1,2- Nc- C (4)h)( CN)(2) one- dimensional chains and one- dimensional arrays of TPPs. The conductivity at room temperature is 0.1 S cm(-1), and the temperature dependence is semiconducting with a small activation energy of about 0.05 eV. The positive temperature- independent value of about 60 mu V deg(-1) observed in the thermoelectric power measurements suggests that the salt is in the correlated hopping regime.

Under a magnetic field, the resistance becomes two orders of magnitude smaller than the zero-field resistance. The magnetic-field-angle dependence of the magnetoresistance reflects the symmetry of the Fe(Pc)(CN)(2) molecule. We discuss, according to the scaling relation, the correlation between the magnetoresistance and the molecular spin fluctuation.

    Thermal analysis of Ag(DM)(2), where DM = 2,5-dimethyl-NN'-dicyanoquinonediimine, clarified that the salt had an insulating amorphous phase (>= 155 degrees C). Characterization of this and related solid states of Ag(DM)(2) indicated that a photo-induced process should be essential in controlling the number of carriers and thus conduction behavior of the salt by illumination. In fact, while heating could do nothing but make the salt insulating when the sample temperature exceeded 155 degrees C, ultraviolet-visible light illumination (< 155 degrees C) could gradually change the properties to be semiconducting with retaining the crystal lattice (average structure).

    Charge disproportionation (CD) recently observed in many organic conductors is reviewed. CD is closely related to the charge ordering (CO) but is observed even when no long range CO is established. In a theta-phase BEDT-TTF salt, (BEDT-TTF)(2)RbZn(SCN)(4), an extremely slow dynainics of CD has been observed above T-MI. A similar phenomenon is also observed in the Cs-analog, (BEDT-TTF)(2)CsZn(SCN)(4). However, a spin-singlet ground State Without CD is suggested in this salt at low temperatures. It is shown that alpha-(BETS)(2)I-3 exhibits CD at low temperatures, as in alpha-(BET-TTF)(2)I-3. Recently, an abnormal line broadening has been observed in C-13-NMR of (TMTSF)(2)FSO3 under pressure as well as in Se-77-NMR of lambda-(BETS)(2)FeCl4 in a high field. We expect that both are very likely caused by a large CD among the organic molecular sites.

    Molecular materials have been recently spotlighted as promising candidates for advanced functional materials. We have developed a novel and simple doping method for a molecular material which utilizes a light-induced solid state reaction. The electrical behavior of a single crystal of a molecular charge-transfer salt of silver(I) ion qualitatively becomes differed after illumination with ultraviolet-visible (UV-VIS) light. The X-ray photoelectron spectroscopy also demonstrated that there was neutral silver species concentrated in the illuminated part of the pressed pellet sample, while only silver (I) ions were detected in the rest part and non-illuminated samples. Raman spectra of the pressed pellet sample showed that the formal charge of the constituent organic pi-acceptor molecule, which is responsible for the conductivity of this material, varied in accordance with the time of illumination. Illumination with UV-VIS light upon only half of a thin single crystal of the same material transformed it to junction structure, exhibiting a rectifying character. This doping method has opened a new way for fabrication of devices from molecular solids.

    Single crystals of mellitate anion ([C-6(COO)(6)H(6-)n](n-)) with piperidinium [C5H10NH2+](3)[C-6(COO)(6)H-3(3-)] (1) and [C5H10NH2+](2)[C-6(COO)(6)H-4(2-)].CH3OH.3H(2)O (2), with 1-methylpiperidinium [C5H10NHCH3+]2[C-6(COO)(6)H-4(2-)]. 2H(2)O (3), and with o-phenylenediammonium [C6H4(NH3)(2)(2+)](2)[C-6(COO)(6)H-2(4-)].2CH(3)OH (4) have been prepared and structurally characterized. In all of the salts, two-dimensional (2D) networks of mellitate anions were formed due to the strong self-organization of the anion. In 1, a 2D hexagon-type network of hydrogen-bond has been observed to form among the anions. This is characteristic of the mellitate anions with n = 3 (n: deprotonation number from the acid). In other salts, a 2D anion network containing either water molecules or -NH3 groups commonly formed. Since the network pattern occurs with different cation species, this hydrogen-bonding unit was determined to be dominant in the n = 2 anion with water and the n = 4 anion with = NH3 species.

    We synthesized TPP[Fe-III(Pc)(CN)(2)](2), PTMA(x)[Fe-III(Pc)(CN)(2)](.)y(MeCN), and PXX [Fe-III(Pc)(CN)(2)], a new series of charge-transfer salts containing the axially-substituted phthalocyanine (Pc), [Fe-III(Pc)(CN)(2)](-) In this molecular unit, the pi conduction electron derived from the Pc-ring coexists with the d electron which is a potential source of a local magnetic moment. Therefore various phenomena associated with the interplay between local magnetic moments and conduction electrons are expected. We observed the giant negative magnetoresistance (GNMR) in all the three salts. The GNMR is highly anisotropic for the magnetic-field direction, and reflects the g-tensor anisotropy of the local magnetic moment in the [Fe-III(Pc)(CN)(2)](-) unit. This indicates that the GNMR in these salts originates from the strong pi-d interaction in the [Fe-III(Pc)(CN)(2)](-) unit. (C) 2004 Elsevier Ltd. All rights reserved.

    Mellitate anions form hydrogen-bonding infinite networks in the salts with pyridinium cations. The network pattern depends on the number of deprotonation (n) from the mellitic acid; for n = 3, triangular hydrogen-bond units form a two-dimensional sheet, while for 11 = 2, dual 14 hydrogen-bond units induce one-dimensional belts or two-dimensional grids. These self-organizing properties have been utilized for the crystal design of the TTF-type radical cation salts. Crystallization with TMTTF gave two kinds of crystals. One of the radical cation salt crystals consists of a channel network of the anions and one-dimensional columns of TMTTF in the channels. In the other TMTTF salt, the anions with n = 1 form a two-dimensional sheet with methanol molecules. The TMTTF radicals are packed between the sheets with their molecular planes parallel to the anion planes.

    We obtained three conducting crystals based on a [Fe-III(Pc)(CN)(2)] molecular unit. All crystals showed a large anisotropic negative magnetoresistance arising from the pi-d interaction self-contained in the [Fe-III(Pc)(CN)(2)] unit. The anisotropy is attributable to the anisotropic g-tensor in the [Fe-III(Pc)(CN)(2)] unit. We also obtained a thin film containing [Fe-III(Pc)(CN)(2)]. The film exhibits photocurrent response for the UV irradiation. These features suggest [M(Pc)(CN)(2)] molecular unit is a well-designed one for a building block of molecular devices.

    In order to examine the possibility of (persistent) carrier doping to molecular crystals by light exposure, some different types of molecular crystals containing photoreactive species are synthesized and characterized. The [Ru(bpy)(3)](2+) cation (bpy = 2,2'-bipyridyl) yielded two different new complexes with [Ni(dmit)(2)](-) radical species, both of which were structurally characterized and turned out to be band insulators. Methy viologen (MV) has been found to yield a new phase of the complex with [Ni(dmit)(2)](-), MV[Ni(dmit)(2)](2). The temperature dependences of electrical resistivity (decreasing with lowering temperature down to 1.0 K) and magnetic susceptibility (Pauli paramagnetism from 300 K to 1.8 K with a hysteresis below - 100 K) clearly indicate that this phase is metallic. The thermoelectric power exhibited similar to0 muVK(-1) from 300 K-4.2 K. This phase turned out to be metastable, and the crystals gradually turned into insulating ones. The effects of UV-VIS light exposure to the conducting and magnetic properties of Ag(DMe-DCNQI)(2) have been studied, and clear differences between the exposed and the pristine crystals were observed. The ESR signal at 3.7 K suggested that the exposed sample should include the Ag(0) species.

    A novel phthalocyanine conductor containing 2-D pi-pi stacks of the partially oxidized Co(Pc)(CN)(2) units has been obtained by the electrochemical oxidation method with PXX. The crystal is highly conductive (> 10(3) S cm(-1)) at all the temperatures measured (5 K < T < 300 K). Though the metallic character becomes clearer compared with the single chain or ladder chain conductors, the 2-D sheet has been found to be still anisotropic.

    The binuclear Cu complex salts of 1,4,7-trithiacyclononane (9S3) with an inorganic anion (BF4)(-) and with an organic radical anion TCNQ(-) (7,7',8,8'-tetracyanoquinodimethanide) were synthesized and their molecular and crystal structures were examined in connection with the magnetic properties. The new complex cation [Cu(9S3)CN(9S3)Cu](+) varies its charges and magnetic properties depending on the counter anions; [Cu(9S3)CN(9S3)Cu](BF4) (1) was obtained as diamagnetic colorless crystals, while [Cu(9S3)CN(9S3)Cu](TCNQ)2 (2) was obtained as dark blue crystals with antiferromagnetic properties. Complex I crystallized in the monoclinic space group C2/c with a = 26.863(2), b = 7.0878(5), c = 13.4864(8) Angstrom, beta = 116.318(2)degrees. Complex 2 crystallized in the triclinic space group P (1) over bar with a = 12.521(1), b = 20.2698(8), c = 8.0205(4) Angstrom, alpha = 100.688(4), beta = 93.846(5), gamma = 94.953(4)degrees. Both complexes are comprised of cyano-bridged two Cu(9S3) ions with tetrahedral coordination. The X-ray structural study revealed that 1 has two crystallographically equivalent copper(l) atoms, while 2 has two crystallographically independent Cu-I/II sites. The two Cu-I/II sites could not be distinguished from the X-ray structural study. For 2 the IR spectra show that both crystallographically independent TCNQ species were monoanions and are strongly dimerized due to pi-stacking, which well explains their diamagnetic contribution to the magnetic susceptibility and the highly insulating property of this salt. The temperature-dependent magnetic susceptibility of 2 showed a deviation from the Curie-Weiss behaviour around 60 K, which indicates a strong antiferromagnetic intermolecular interaction between the copper complexes and that such intermolecular interaction should partly occur via the TCNQ radical anion dimer.

    Solid state properties of dicyano(2,3-naphthalocyaninato)cobalt(III) neutral radical crystal, [Co(2,3-Nc)(CN)(2)]CH3CN, were characterized by measurements of the resistivity under high pressure and under uniaxial strain, thermoelectric power, magnetic susceptibility, ESR and polarized reflectance spectra. The title compound exhibited thermally activated-type electrical conductivity along the c-axis. The room temperature (RT) resistivity rho(RT) along the c-axis and activation energy E-a rapidly decreased with increasing pressure. The temperature-dependent thermoelectric power S was that of a typical one-dimensional (ID) semiconductor. However the high absolute value of S suggested that this electronic system should be strongly correlated. Although the electrical resistivity exhibited monotonous temperature-dependence, the magnetic susceptibility clearly indicated a Peierls-type transition and marked fluctuation from RT. Both Peierls-type transitions and fluctuations are characteristic phenomena to 1D conductors. Furthermore ESR spectra manifested that the Peierls-type transition occurred at 100 K. The inconsistency between the electrical behavior (without a phase-transition) and magnetic behavior (with a phase-transition) indicates separation of the degrees of freedom in spin and charge (spin-charge separation) of this material. Spin-charge separation is a theoretically predicted phenomenon peculiar to the ID conductors with strong correlation. The reflectance spectra were quantitatively explained by a 1D Hubbard model, and manifested the existence of a structural fluctuation of this material from RT. Based on these observed physical properties it is concluded that [Co(2,3-Nc)(CN),]CH,CN is a strongly correlated ID semiconductor with a Mott(Hubbard) type energy gap and characterised with a fluctuation and spin-charge separation.

    An organic charge-transfer (CT) salt (BEDT-TTF)(3)(MnCl3)(2)(C2H5OH)(2) has been synthesized by a standard electrochemical method. The crystal data are monoclinic, C2/c (#15), a = 38.863(4) Angstrom, b = 6.716(1) Angstrom, c = 23.608(3) Angstrom, beta = 115.007(3)degrees, V = 5584(1) Angstrom(3), and Z = 4. The structure consists of one-dimensional (1D) infinite {[MnCl3](-)}(infinity) magnetic chains and two-dimensional (2D) organic conduction pathways. The former consists of face-sharing octahedra of manganese chloride complex ions, and dominates the magnetic properties of this compound. Such a feature of the crystal structure closely relates to transition metal hexagonal perovskite compounds, all of which are known for frustrated triangular lattices comprised of weakly interacting 1D magnetic chains. The new compound exhibits a high conductivity down to 4 K. (C) 2003 Elsevier Inc. All rights reserved.

    A novel low-dimensional molecular conductor, [PXX][Fe-III(Pc)(CN)(2)], has been synthesized. This salt contains the magnetic Fe-III ion (S = 1/2), and is isomorphous with [PXX][Co-III(Pc)(CN)(2)] which includes the non-magnetic Co-III ion. In both salts, the [M-III(Pc)(CN)(2)] (M = Fe or Co) units form a two-leg ladder chain. The two salts exhibit a similar temperature dependence of the thermoelectric power and a similar reflectance spectrum. The Fe-III salt shows serniconducting behavior in its electrical resistivity over the temperature range measured, while the isomorphous Co-III salt exhibits metallic behavior in its resistivity above 100 K. The difference in the transport properties between the two salts suggests that the conduction electrons in the Fe-III salt are seriously scattered by the local magnetic moment. Spontaneous magnetization is observed below 8 K in the Felt salt. Upon applying a magnetic field, the resistivity of the Fe-III salt drastically decreases below 50 K. The decrease in the resistivity is highly anisotropic to the field orientation. The field orientation dependence is highly consistent with the g-tensor anisotropy in the [Fe-III(Pc)(CN)(2)] unit, suggesting that the negative magnetoresistance originates from the large pi-d interaction self-contained in the [Fe-III(Pc)(CN)(2)] unit.

    The magnetic torque shows the anomaly around 20K. The torque curve suggests the antiferromagnetic state in the one-dimensional Fe(Pc)(CN)(2) chain. The magnetic easy axis is directed along the CN-ligand in the Fe(Pc)(CN)(2) unit. Because of the strong spin-orbit coupling, the next highest occupied molecular orbital is also ordered so that the molecular orbital angular momentum of the neighboring Fe(Pc)(CN)(2) unit is antiparallel. We observed the weak ferromagnetism below 6K. This is ascribed to the canting of the antiparallel moments.

At x = 1, the system shows anisotropic Curie-Weiss behavior and spontaneous magnetization below 6 K The temperature below which spontaneous magnetization occurs (T-c) shifts downward with a decrease in Fe-III concentration, but is still above 2 K at x = 0.07. The anisotropic Curie-Weiss behavior in the susceptibility was observed for all the alloys measured. This magnetic anisotropy was associated with the g-tensor anisotropy in the [Fe-III...(Pc)(CN)(2)] unit.

    We measured the electron spin resonance and the magnetoresistance in the iron(Ill) phthalocyanine complexes. The electron spin resonance in PNP[Fe(Pc)(CN)(2)] reveals the large anisotropy of the g-value. This is due to the strong spin-orbit coupling in the second HOMO (the third HOMO) hybridizing the d(yz)(d(zx)) orbital in the central Fe atom. This anisotropic g-value is consistent with the anisotropy of the magnetic susceptibility and the negative magnetoresistance in TPP[Fe(Pc)(CN)(2)](2). We also measured the large negative magnetoresistance in [PXX][Fe(Pc)(CN)(2)] and (PTMA)(x)[Fe(Pc)(CN)(2)](y)(CH3CN).

    Electrochemical oxidation of [Co-III(Pc)X-2](-) yields highly conducting partially oxidized salt crystals. Their crystal structures and dimensionality of the pi-pi interaction (electronic system) vary by the cationic species in the salts; one-dimensional for TPP (tetraphenylphosphonium) or PTMA (phenyltrimethylammonium) cations, and ladder and two-dimensional for the PXX (peri-xanthenoxanthene) radical cation. Substitution of the axial group (X) or extension of the pi-conjugated macrocycle (Pc) has been found to influence the magnitude of the pi-pi stacking interactions. Their electrical properties characterized by the conductivity and thermoelectric power measurements are found to be dependent on the dimensionality and the magnitude of pi-pi stacking interactions.

    The title salt was obtained as fine black needles from the electrolysis of ET (ET: bis(ethylenedithio)tetrathiafulvalene) with a Mn cluster in 1,1,2-trichloroethane containing 10% of ethanol. The conductivity at room temperature was 25 S cm(-1) with weakly semiconducting behavior, yet the salt kept a high conductivity down to 4 K (similar to0.1 S cm(-1)). The manganese(II) chloride anion formed an infinite chain made of face-shared MnCl6 octahedrons, and these chains formed insulating sheets with ethanol molecules between the chains. The ET cation radicals formed alpha'-type conducting sheets between the insulating sheets. Such crystal structure was characterized as that of a typical hexagonal perovskite ABX(3), where A equals to a bulky monocation. The magnetic behavior was reproduced by the Curie-Weiss law, which might be attributable to the face-shared MnCl6 octahedron chains. (C) 2002 Elsevier Science B.V. All rights reserved.

These three salts have similar columnar structures, nevertheless exhibit different electrical behaviors. TPP[Fe(Pc)(CN)(2)](2) exhibits anisotropic giant negative magnetoresistance, while TPP[Co(Pc)(CN)(2)] exhibits large positive magnetoresistance. The alloyed compound, TPP[Fe-0.30 Co-0.70 (Pc)(CN)(2)](2), also exhibits anisotropic negative magnetoresistance, although the decrease in the resistivity under the magnetic field is less than that of TPP[Fe(Pc)(CN)(2)](2). The g-tensor anisotropy in the [Fe(Pc)(CN)(2)] unit qualitatively explains the field-orientation dependence of the negative magnetoresistance. Magnetic fluctuation associated with a weak-ferromagnetic transition is suggested as a possible origin of the giant negative magnetoresistance. (C) 2002 Elsevier Science (USA).

All of these crystals are composed of a multi-dimensional network of the Ni(dMit)(2) anions and the hydrogen-bonding one-dimensional cation chains. Compared with tight hydrogen bonds in the P = P and P-P chains, that in the PP chain is rather loose. The P = P and P-P salts show semiconducting behavior with high resistivity and large activation energy, while the PP salt shows the opposite temperature dependence with low resistivity at high temperature. The thermoelectric power indicates that the PP salt is an n-doped semiconductor. The proton defects may occur in the loosely bound PP chain which results in the carrier doping in the conduction band formed by the pi-pi interaction of the Ni(dmit)(2) anion radicals.

We proposed the field-induced reduction of the spin scattering of the conduction electrons by the local moments as the origin of the negative magnetoresistance. In the isostructural compound TPP[Co(Pc)(CN)(2)](2) without magnetic moments, we observed large positive magnetoresistance. The experimental result of the Go-compound suggests that the local moments are essential for the mechanism of the negative magnetoresistance of the Fe-compound.

    Electrochemical oxidation of PTMA[M-III(Pc)(CN)(2)] (PTMA=phenyltrimethylammonium, Pc=phthalocyaninato, and M=Co or Fe) gives partially oxidized salts (PTMA)(x)[M-III(Pc)(CN)(2)].y(solvent) (solvent=acetonitrile or acetone). The obtained crystals in which the solvent molecules partially occupy the cationic sites are isomorphous regardless of M and solvent. They are highly conducting and metallic behavior is observed in the conductivity and thermoelectric power measurements. In contrast to the Pauli-like behavior of the Co-III salt, Curie-like behavior with an anomaly due to antiferromagnetic interactions was observed for the Fe-III salt in magnetic susceptibility measurements. The existence of local magnetic moments in the Fe-III salt leads to a significant influence on the transport properties, suggesting the existence of pi -d interactions in this system.

    Air-oxidation of the acetone-acetic acid solution Of (C7H13NH)(2)[Pd(dmit)(2)] yielded black shiny platelets of (C7H13NH)[Pd(dmit)(2)](2). The crystal structure was characterized by a criss-cross columnar structure, which has been often observed in M(dmit)(2)-based (M = Ni, Pd) superconductors. Although the quinuclidinium cation (C7H13NH)(+) is found to be orientationally disordered on a 2-fold axis, the crystal exhibited metallic conductivity down to similar to 40 K. Under ambient pressure the room temperature conductivity is around 22 S cm(-1) and the resistivity gradually decreased with decreasing temperature down to 200 K, where it suddenly started to decrease more rapidly and kept decreasing down to similar to 40 K, where it started to increase steeply. At ea. 200 K the structural transition occurred, yet the crystal and molecular structures remained practically unaffected including the cation site disorder and the strong dimerization of the Pd(dmit)(2) molecules. The electrical behaviour under high pressure was rather unusual but could be compared with structurally related Pd(dmit)(2)-based superconductors.

    A charge-transfer complex of DAP with F(4)TCNQ has been obtained by electrochemical reduction of F4TCNQ in acetonitrile in the presence of DAP . BF4. The crystal comprises segregated one-dimensional columns of donors and accepters with CH3CN as the crystal solvent. The molecular geometry and infrared spectrum show that the donor and acceptor components are completely ionized. These features are the same as those found in DAP.TCNQ. However, a marked difference lies in the column structure; both the DAP and F4TCNQ columns are composed of the dimerized units, while they are uniform in DAP.TCNQ. The difference can be accounted by the increase of the transfer energy in DAP .F(4)TCNQ . CH3CN compared with DAP.TCNQ.

    We have found giant negative magnetoresistance in the one-dimensional conductor TPP[Fe(Pc)(CN)(2)](2) below 50 K. The reduction of the resistance is larger in the field perpendicular to the one-dimensional axis than parallel to the axis. The magnetic susceptibility shows anisotropic Curie-Weiss behavior. The experimental results suggest the interaction between the one-dimensional electron system and the local moments. The reduction of the spin scattering of the itinerant electrons by the local moments under the field is proposed as the origin of the giant negative magnetoresistance.

    Electrochemical oxidation of the dicyano(2,3-naphthalocyanato)cobalt(III) anion ([Co(2,3-Nc)(CN)(2)](-)) yields electrically conducting crystals comprised of the Co(2,3-Nc)(CN)(2) neutral radicals and some crystal solvents. The oxidation of the potassium salt in acetonitrile gives Co(2,3-Nc)(CN)(2). CH3CN, while that in a mixed solvent of acetonitrile/o-dichlorobenzene (DCB) gives Co(2,3-Nc)(CN)(2). 2DCB. X-Ray structure analyses show that two- or three-dimensional pi-pi stacking interactions are achieved in these crystals. Compared with the phthalocyanine (Pc) derivatives this higher-dimensionality in the 2,3-Nc radical crystals, even with a large crystal solvent, arises from the linear extension of the pi-conjugation system of Pc.

    The magnetoresistance of alpha-[(CH3)(2)(C2H5)(2)N][Ni(dmit)(2)](2) has been studied at ambient pressure in magnetic fields of up to 60 T and under hydrostatic pressures of up to 6 kbar in fields of up to 17 T. The high field measurements indicate a very simple Fermi surface. Measurements in medium fields, however, indicate several quantum oscillation frequencies, whose weight gets reduced with increasing field in favour of the major gamma-orbit. The low field alpha- and beta-orbits exhibit a strong pressure sensitivity. Whereas no quantum oscillations were observed at 2 kbar, shifted alpha-and beta-frequencies occur at a pressure of 6 kbar.

    The tautomeric structures in solid phase were studied by near-edge X-ray absorption fine structure (NEXAFS) and X-ray photoelectron spectroscopy (XPS) for five N-salicylideneaniline derivatives. The observed features in the NEXAFS spectra were assigned by (1) the comparison with the core excitation spectra of reference compounds and (2) ab initio MO calculations of the core-excited states by the improved virtual orbital method. The relative intensity of the observed peaks characteristic of each tautomer enabled us to deduce the tautomeric structures of these compounds. The XPS spectra allowed quantitative estimation of the relative tautomer populations. These structures are consistent with the previous estimation by Xray diffraction. These results demonstrate the usefulness of NEXAFS as well as XPS for studying the tautomerism in hydrogen bonded systems.

    A highly conducting partially oxidized salt of TPP[Co(Pc)(CN)(2)](2) can be obtained by electrocrystallization of TPP[Co(Pc)(CN)(2)]. The crystal is composed of one-dimensional TPP arrays surrounded by slipped-stacked one-dimensional [Co(Pc)(CN)(2)] chains. The electrical conductivity at room temperature is quite high, 120 Omega(-1) cm(-1), though at low temperature it is weakly semiconducting. The band width for this stacking mode has been estimated from both thermoelectric power measurements and an extended Huckel calculation. The latter suggests that the band width value for the slipped-stacking mode is about 40% of the value for the face-to-face stacking mode. The width estimated from the metallic temperature dependence of the thermoelectric power is actually in excellent agreement with that estimated from the calculation.

    lambda-(BETS)(2)FeCl4, where BETS is bis(ethylenedithio)tetraselenafulvalene, is an organic molecular metal with magnetic anions. It undergoes a metal-insulator transition at about TM-I similar to 8 K. This insulating state can be suppressed and a metallic or highly-conducting state can be restored by applying external magnetic field higher than 10 T. The nature of this phase transition and the ground state, whether a spin-Peierls or antiferromagnet, has not been clarified. In this paper, we report the anisotropy of magnetic properties of lambda-(BETS)(2)FeCl4 studied using SQUID magnetometer. The temperature dependence of the static magnetic susceptibility below TM-I was found to show a strong field dependence when the field is applied parallel to the crystalline long axis (H//c). The nonlinear behavior in magnetization (M-H), reminiscent of a spin-flop transition of antiferromagnet, is observed at magnetic fields around 1 T, well below the field necessary for restoration of highly-conducting state. This strong field dependence is absent for other magnetic field directions, suggesting that the groundstate of lambda-(BETS)(2)FeCl4 is antiferromagnet rather than spin-Peierls.

The cyclotron masses for both orbits were estimated to be 1.2m(e) and cm 2.4m(e), respectively. In addition to these SdH oscillations an oscillation attributable to Stark quantum interference (SQI) was observed. The data of ADMRO revealed that the shape of Fermi surface is consistent with the extended Huckel calculation.

    The temperature dependence of the electrical resistivity of (DED)(2)PF6(THF)(2), where DED is thiadiazoleethylenedithiodiselenadithiafulvalene, is metallic down to similar to 20 K. At lower temperatures the resistivity rises proportionally to the logarithm of temperature, followed by a saturation of the resistivity upturn at around 1 K. The magnetic susceptibility exhibits Curie-like behavior down to similar to 20 K, and chi T suddenly goes towards zero at lower temperatures. Such behaviour indicates that this salt could be a rare example of 'purely organic' systems whose electrical behavior at low temperatures might be best explained as a result of Kondo effect.

The onset of the diamagnetic transition occurred at 1.39 K. From the measurements of the Meissner effect, the volume fraction of the superconducting phase was estimated to be more than 62%. From the measurements of the diamagnetic shielding effect, this fraction was estimated to be about 93%. This high level of volume fraction shows that the superconducting phase is the main phase in alpha-EDT-TTF[Ni(dmit)(2)].

BETS(2)FeCl(4) has two modifications (kappa and lambda). Unlike kappa-BETS(2)FeCl(4) with stable metallic state down to 2 K, lambda-BETS(2)FeCl(4) exhibited a cooperative electric (metal-insulator) and magnetic (paramagnetic-antiferromagnetic) transition at 8 K. BETS(4)Cu(2)Cl(6) with theta-type arrangement of BETS molecules is metallic down to 4 K. Two Cu2+ ions are bridged by two Cl atoms to form binuclear magnetic anion Cu2Cl62-. The Crystal structure and the temperature dependence of the magnetic susceptibility were briefly described.

Pressure and temperature dependencies of the resistivities of lambda-BETS(2)GaX(x)Y(4-x) closely resemble those of kappa-type BEDT-TTF superconductors. Many BETS metals with magnetic ions (Fe3+, Mn2+, Co2+, Cu2+) were prepared. Among them, kappa-type MX(4) (M=Fe, Co; X=Cl, Br) salts and theta-type Cu2Cl6 salts are metallic down to at least 4 K. The static susceptibility of lambda-BETS(2)FeCl(4) shows a characteristic magnetic field dependence below its metal-insulator transition temperature.

    Crystals of kappa-(BEDT-TTF)(2)I-3 have been prepared electrochemically from a tetrahydrofuran (THF) solution containing the mixed supporting electrolytes {[(C4H9)(4)N]I-3 (95%)-[(C4H9)(4)N]AuI2 (5%)} and also from a THF solution without [(C4H9)(4)]AuI2. A resistivity drop indicating a superconducting transition was observed at 4.2 K (mid-point). The T-c decreased with increasing pressure (dT(c)/dP = -0.8 K kbar(-1)). The resistivity exhibited an anomaly around 170 K, which was coupled with the structural phase transition accompanied by the change of the space group (P2(1)/c-->P2(1)). The crystal structure was determined at 295, 150 and 10 K. The extinction rule of the X-ray intensity data collected at 295 K confirmed the space group to be P2(1)/c as reported previously. The (h 0 l) reflections at 150 and 10 K revealed the absence of c-glide symmetry. The low-temperature crystal structure analyses showed conformational change of the ethylene groups. The low-temperature band structure calculation based on a simple extended Huckel approximation gave Fermi surfaces consistent with de Haas-van Alphen experiments.

    alpha-(EDT-TTF)[Ni(dmit)(2)] comprises crossing columns of EDT-TTF and Ni(dmit)(2) and exhibits unique metallic behaviour with a characteristic resistivity peak at around 14 K. The possibility of the development of the superstructure was examined down to 9 K by using a low-temperature imaging plate X-ray system, but no extra X-ray reflections could be found below 14 K. The 14 K anomaly is, therefore, thought not to originate from charge density wave (CDW) instability New phases of gamma-(EDT-TTF)[Pd(dmit)(2)] and gamma-(EDT-TTF)[Ni(dmit)(2)] were found. gamma-(EDT-TTF)[Pd(dmit)(2)] has parallel columns of EDT-TTF and Pd(dmit)(2) and shows a resistivity anomaly around 80 K. Below 80 K, X-ray satellite reflections indicating CDW formation were observed. gamma-(EDT-TTF)[Ni(dmit)(2)] undergoes a metal-insulator transition at around 100 K.

    A new organic superconductor, lambda-BETS(2)GaBrCl(3), exhibits an onset of the superconducting transition at 7.5-10 K with a broad resistivity maximum at 55-60 K and a second resistivity increase below ca. 15 K, probably related to the electron localization effect owing to disorder of the tetrahedral anions; the superconducting state persists up to 14 kbar.

    The very sharp metal-insulator transition, which occurs at 8 K at ambient pressure in lambda-(BETS)(2)FeCl4 is suppressed when applying magnetic fields > 10T. This unusual phenomenon may be connected to ferromagnetic ordering of the Fe3+ moments, which could drive some ''evaporation'' of the previously condensed conduction electrons, into a field-restored highly conducting state (FRHCS) in which oscillations of the magnetoresistance are reported.

    We report on the magnetotransport properties, up to 37 T, of the first organic conductor containing magnetic Fe3+ ions, lambda-(BETS)(2)FeCl4, where BETS is bis(ethylenedithio)tetraselenafulvalene. The previously reported very sharp metal-insulator phase transition, which occurs at 8 K under ambient pressure, is suppressed when applying magnetic fields > 10 T. This unusual phenomenon may be connected to a field-induced ferromagnetic ordering of the Fe3+ ion moments. This could result in some kind of ''evaporation'' of the previously condensed carriers, into a field-restored highly conducting state (FRHCS). In this ground state, angular dependence of the magnetoresistance is observed for current flowing perpendicularly to the best-conduction c axis.

    We present experimental evidences showing coexistence of superconductivity with CDW (or SDW) in alpha-EDT-TTF[Ni(dmit)(2)], a new ambient-pressure superconductor with donor-acceptor structure. The electrical resistance of this salt exhibits a hump around 10 similar to 14 K and drops at 1.3 K due to the superconducting transition. Based on the electrical anisotropy derived from reflectance spectra and weak-field magnetoresistance, this resistance hump is assigned to the CDW (or SDW) formation within EDT-TTF chain. Above 20 K both EDT-TTF and Ni(dmit)(2) chain contribute to the electrical conduction, while below 10 K electrical conduction is mainly through Ni(dmit)(2) chain. Temperature-pressure phase diagram determined by resistance measurements under pressure is presented.

    Crystal structures and electronic properties of BETS compounds with tetrahedral anions, MX(4) (BETS=bis(ethylenedithio)tetraselenafulvalene: M=Ga; Fe, In; X=Cl, Br) were examined. The salts can be classified into two types (kappa, lambda). All the compounds with so-called kappa-type molecular arrangements retained metallic behavior down to 4 K. lambda-(BETS)(2)GaCl4 demonstrated a a superconducting transition around 8 K. Whereas lambda-(BETS)(2)FeCl4 with the isomorphic h-type structure exhibited a sharp metal-insulator transition at 8 K. Low-temperature X-ray studies showed that the structural difference between lambda-GaCl4 and lambda-FeCl4 salts is very small. The structure analysis of kappa-(BETS)(2)FeCl4 at 18 K indicated that the FeCl4 anion has approximately C-3v symmetry. The ESR measurements revealed the high-spin state of Fe3+ in lambda-FeCl4 salt and and low-spin state in kappa-FeCl4 salt. ESR intensities of kappa- and lambda-FeCl4 salts suggested antiferromagnetic interaction between Fe3+ ions.

    The electrical and optical properties were studied concerning alpha-(BETS)(2)I-3 and alpha-(BEDT-STF)(2)I-3, which are isostructural to alpha-(BEDT-TTF)(2)I-3. It has been shown that alpha-(BETS)(2)I-3 and alpha-(BEDT-STF)(2)I-3 undergo metal-insulator transitions at around 50 and 80 K, respectively, and that their electrical resistivities exhibit temperature dependences resembling that of alpha-(BEDT-TTF)(2)I-3 under high pressure. The optical reflectance spectra of these salts show a two-dimensional nature of their electronic structures, and analyses of the spectral data show that the transverse inter-molecular interaction increases in the order alpha-(BEDT-TTF)(2)I-3 < alpha-(BEDT-STF)(2)I-3 < alpha-(BETS)(2)I-3.

    Magnetotransport properties of two isostructural salts, the superconducting lambda-(BETS)2GaCl4 phase and the first organic conductor containing magnetic Fe3+ ions, lambda-(BETS)2FeCl4, where BETS is bis(ethylenedithio)tetraselenafulvalene, have been studied up to 37 T. The previously reported sharp metal-insulator phase transition occurring at 8 K under ambient pressure for lambda-(BETS)2FeCl4 is suppressed when applying magnetic fields > 10 T. This unusual phenomenon may be connected to a field-induced ferromagnetic ordering of the Fe3+-ions moments. This could result in some kind of ''decondensation'' of the carriers, initially condensed below 8 K, into a field-restored highly conducting state (FRHCS). The temperature-magnetic-field (T-H) phase diagram is presented. The angle dependence of the critical field H(c2) has been determined for the superconducting lambda-(BETS)2GaCl4 phase at 4.2 K.

    The crystal structures and/or electrical properties of EOTT2X [X = AuCl2, AuBr2, Aul2, Au(CN)2, Ag(CN)2, ICl2, IBr2, I2Br, I3, Br3 and MnCl4, FeCl4, CoCl4, NiCl4] are reported. Concerning the linear anion salts seven (X = AuBr2, Aul2, ICl2, I2Br, I3, Br3) of them were found to be isostructural. Although they apparently have columnar structures, there are many sulfur-sulfur short contacts, which lead to a two-dimensional network in the donor sheet. Their Fermi surfaces were calculated to be closed and elliptical by the tight-binding band approximation. EOTT2FeCl4 is disordered at the anion site and has a dimeric columnar structure along the a axis. The Aul2 salt is metallic down to low temperatures. The IBr2 salt also exhibited decreased resistivity with an inflexion at ca. 110 K and a sample-dependent minimum around 25 K. The metal-insulator (M-I) transitions occurred in AuBr2, ICl2 and Br3 salts at temperatures > 100 K. The other salts [I3, I2Br, AuCl2, Au(CN)2, Ag(CN)2, FeCl4, NiCl4, MnCl4 and CoCl4] are semiconductors. EOTTICl2 is polymorphic: the alpha-type is isostructural with the other linear anion salts with an M-I transition around 145 K. The beta-type is semiconducting and has a dimeric structure. The M-I transition of alpha-EOTT2ICl2 might be explained by a structural transition to a similar insulating state to the beta-type.

    An unsymmetrical donor 4,5-ethylenedithio-4',5'-(2-oxatrimethylenedithio)-diselenadithiafulvalene (EOST)dagger has been synthesized. Single crystals of some charge-transfer salts of EOST have been prepared electrochemically. The crystal structures of EOST and its charge-transfer salts were analysed by X-ray crystallography. The dc resistivities were measured on the single crystals. Eight of the salts with linear anions [(EOST)2I3, alpha-(EOST)2IBr2, beta-type IBr2 salt, (EOST)2ICl2, (EOST)2I2Br, alpha- and beta-type AuBr2 salts and Au(CN)2 salt] retained their metallic conductivity down to low temperatures (less-than-or-equal-to 35 K) and some were found to be isostructural. The overlap integrals of some salts and the tight-binding band was examined for (EOST)2I3. The result suggested that it has a quasi-one-dimensional electronic structure and that EOST molecules interact most strongly in a side-by-side direction. The crystal and electronic structures of (EOST)2I3 are discussed by comparison with the isostructural compound (EOTT)2IBr2 [EOTT: 4,5-ethylenedithio-4',5'-(2-oxatrimethylenedithio)tetrathiafulvalene].

    High-pressure resistivity studies on beta-[(CH3)4N][Pd(dmit)2]2 and [(CH3C2H5)2N]-{Pd(dmit)2]2 have revealed the system to be new molecular superconductors with Tc=6.3 K at 6.5 kbar and Tc=4K at 2.4kbar, respectively, beta-[(CH3)4][Pd(dmit)2]2 has the structure almost isomorphous to the high-pressure superconductor, [(CH3)4N][Ni(dmit)2]2, though they have the dimeric columns of Pd(dmit)2 molecules. The determination of the phase diagram has revealed the existence of a narrow temperature region where the superconducting phase invades into the insulating phase. The crystal of [(CH3)2(C2H5)2N][Pd(dmit)2]2 belongs to triclinic system and has the dimeric columns of Pd(dmit)2. It is of interest that the insulating phase emerges when superconducting state is suppressed at high pressure.

    Alpha-BETS2I3 and alpha-(BEDT-STF)2I3, which are analogous of alpha-(BEDT-TTF)2I3, exhibit a metal-insulator-(M-I) transition. Polarized reflectance spectrum and magnetoresistarice under high pressure were studied on these salts in order to investigate the electronic structures and the phase transition. The change of reflectance spectrum accompanying M-1 transition was found to be considerably smaller in alpha-BETS2I3 and alpha-(BEDT-STF)2I3 than in alpha-(BEDT-TTF)2I3. Application of pressure suppresses the M-1 transition for both salts. Alpha-BETS2I3 becomes metallic under 9Kbar over the whole temperature region. A large positive magnetoresistance is observed in this metallic state alpha-BETS2I3 even at relatively high temperature.

    The electrical resistivities of organic metals with kappa-type molecular arrangements were examined. Superconducting transition temperature (T(c)) of alloy system kappa-[(ET)1-x(STF)x]2 Cu[N(CN)2]Br (ET=BEDT-TTF, STF=BEDT-DSeDTF) is rapidly depressed with increase of the doping amount of the asymmetric pi-donor STF. T(c) becomes lower than 1.6 K at x>0.25 but the system retains metallic state at least up to x=0.6. The characteristic resistivity maximum is smeared with increasing x. The metal-insultor transition of kappa-ET2Au(CN)2 at 70 K is suppressed by applying ''soft pressure'' of about 550 bar. The electrical properties and the crystal structures of kappa-MT2Cu[N (CN)2]X (MT=BMDT-TTF, X=Cl Br) were also examined. The crystal of kappa-MT2Cu[N(CN)2]X belongs to monoclinic system with space group Cc. The structure of anion sheet closely resembles that of kappa-MT2Cu[N(CN)2]X. The electrical resistivity decreases monotonously down to 2 K.

The crystal structures and electrical conductivities of radical salts of BEDT-STF, EDST and EOST were examined.

    Several BEDT-TTF salts were synthesized. BEDT-TTF3Br2 and BEDT-TTF-C(CN)3-CuCN were metallic down to 4.2 K. The crystal structure of the former salt was determined. New multi-sulfur TTF derivatives (OTHT, TOTT, and ETT) were synthesized, and their ion-radical salts were obtained by an electrochemical method. We also obtained new donor molecules containing six or seven sulfur atoms which were expected to give new conducting organic salts with two-dimensional electrical properties.

    Electrical and structural properties of (R1R2-DCNQI)2M (R1, R2=CH3, Br..., M=Cu, Li,...) were studied. The IR evidence of the mixed-valency of Cu in (MeX-DCNQI)2Cu (X=CH3, Br) is presented. The 10% doping of DBr-DCNQI induces the metal instability of (DMe-DCNQI)2Cu. The three-fold structure develops below the sharp metal-insulator (MI) transition temperature, which suggests the universality of the three-fold structure in the insulating state of DCNQI-Cu system. The P-T phase diagram is depicted. The characteristic ''reentrant metal region'' will be related to the possible existence of ''molecular heavy elecron system''. The metallic state of (MeBr-DCNQI)2Cu was stabilized by doping Li in the Cu sites. The low-temperature X-my crystal structure analysis of three-fold structure of (MeBr-DCNQI)2Cu was made. A simple model of the antiferromagnetic spin tructure is proposed.

    Polarized reflectance spectra of single crystals of (CH3)4As[Pd(dmit)2]2 and Cs[Pd(dmit)2]2 were measured and compared with those of (CH3)4N[Ni(dmit)2]2. Prominent absorption bands, which do not exist in the reflectance spectra of (CH3)4N[Ni(dmit)2]2 were observed around 10000 cm-1 in the spectra of [Pd(dmit)2] salts. Analysis of the reflectance spectra reveals the anomalous electronic structure in these salts where the energy levels derived from HOMO and LUMO of one molecule are partly inverted due to their strongly dimerized structure.

    Curie temperature T-C of spin arrangement with arbitrary dimension was considered. We assumed that interaction of a spin with all other spins vary with a power-law decay rate in exchange integral on Heisenberg model. As a result, we found that T-C, which was obtained from T-C = lambda C (lambda: mean-field coefficient and C: Curie constant), significantly depends on fractal dimension of spin arrangements D, the exchange integral and the decay constant. This semi-quantitatively explains how T-C depends on D (1 <= D <= 3) in a universal way and also the finite size effect on T-C in low-dimensional spin systems.

    Magnetic properties of organic charge transfer salts Ag(DX)(2) (DX = 2,5-dihalogeno-N,N'-dicyanoquino-nediimine; X = Cl, Br, 1) were modified by UV irradiation from paramagnetism to diamagnetism in an irreversible way. The temperature dependence of susceptibility revealed that such change in magnetic behavior could be Continuously controlled by the duration of irradiation. The observation with scanning electron microprobe revealed that the original appearance of samples, e.g. black well-defined needle-shaped shiny single crystals, remained after irradiation irrespective of the irradiation conditions and the duration. Thermochemical analysis and X-ray diffraction Study demonstrated that the change in the physical properties were due to (partial) decomposition of Ag(DX)(2) to AgX, which was incorporated in the original Ag(DX)(2) lattices. Because the physical properties of low-dimensional organic conductors are very sensitive to lattice defects, even a small amount of AgX could effectively modify the electronic properties of Ag(DX)(2) Without making the original crystalline appearance collapse.

    The strongly nonlinear current-voltage (I-V) characteristics and the large negative magnetoresistance (MR) are observed at low temperatures in the one-dimensional organic conductor TPP[Fe(Pc)(CN)(2)](2). The nonlinear I-V curves are interpreted as the transport of the electrons and holes excited from the charge ordered state on the Fe(Pc)(CN)(2) chains, whose energy gap strongly depends on electric fields. The negative MR is enhanced as temperature decreases, and the resistance steeply changes over four orders of magnitude around 15 T at 1.5 K. This decrease is associated with a magnetic torque anomaly, and the energy gap is rapidly reduced around 15 T. The detailed analyses of the I-V curves show that the electric flux distribution, i.e., the dimensionality of the Coulomb interaction between the carriers, also changes around 15 T.

    Magnetic torque (3 < T < 46 K), dc magnetic susceptibility (2 < T < 300 K), and ac magnetic susceptibility (2 < T < 30 K) are reported for PTMA(0.5)[Fe(Pc)(CN)(2)]center dot CH3CN. The torque curves exhibit a sinusoidal line shape for temperatures above 6 K. This result as well as the temperature dependence of the dc magnetic susceptibility above 13 K was analyzed by employing an anisotropic Heisenberg model in one dimension. The compound exhibits spontaneous magnetization below 6 K. The torque measurements at 3 K revealed that the direction of this spontaneous magnetization is parallel to the easy axis of the mother antiferromagnetism. The ac susceptibility measurements demonstrated the fluctuation of the spontaneous magnetization up to 13 K. A model of charge-ordered ferrimagnetism is proposed in order to explain these results. This model explains the spontaneous magnetization which commonly appears in conducting salts of [Fe(Pc)(CN)(2)] and their derivatives.

    Magnetic torque and heat capacity measurements on TPP[Fe(Pc)(CN)(2)](2) are reported. The torque curves for the magnetic field rotated within the ab plane have a fourfold symmetry, exhibiting inversions around 13 and 27 K. The heat capacity exhibits a broad peak around T = 16.5 K. By applying the magnetic field along the c axis, the maximum value of the heat capacity is enhanced below 20 K. These results, as well as the magnetic susceptibility, were analyzed by employing a numerical calculation based on the anisotropic Heisenberg model in one dimension. The analyses revealed that: (i) the peak in the magnetic-susceptibility data around 25 K is due to an antiferromagnetic short-range order (SRO) formation associated with d electrons, and (ii) pi electrons fall into an antiferromagnetic state below 13 K. The spin-flop field of pi electrons is approximately 80 kOe at 9 K.

    A photoinduced electrical conductivity switching is observed in the molecular conductor of alpha-[bis(ethylenedithio)tetrathiafulvalene](2)I-3 at different temperatures with different irradiation light intensities. The threshold voltage for the differential-negative-resistance effect appearing in the current-voltage characteristic curve decreases and increases, respectively, as the light intensity is increased and as the temperature decreases below the insulator-metal phase transition. The potential application of molecular conductor in bidirectional light-activated thyristor devices is demonstrated. (c) 2007 American Institute of Physics.

    We present a novel way to fabricate electronic devices from a molecular charge transfer salt Ag(DM)(2) by simple illumination, which realizes a junction-structure in the single molecular crystal. The electrical conductivity of the selected parts of samples can be controlled by illimination time and power. The electrical behavior gradually turned semiconducting from metallic one by illumination. X-ray photoelectron spectroscopy, Raman spectroscopy and X-ray absorption fine structure indicated that illumination should transfer some electrons from the conducting DM columns to the Ag ions. The X-ray powder diffraction pattern indicated that original crystal lattice was maintained after the illumination. These observations imply that the illumination practically effected doping (or rather dedoping) on the material. (c) 2006 Elsevier B.V. All rights reserved.

    We measured the static magnetic susceptibility and the electron spin resonance of the Fe(Pc)(CN)(2) complexes, and investigated the molecular magnetism of the unit Fe(Pc)(CN)(2). The magnetic susceptibility shows a highly anisotropic Curie behavior. Based on the electron spin resonance, we found a highly anisotropic g-value (g(1) = 3.62, g(2) = 1.11, and g(3) = 0.52) in the molecular unit Fe(Pc)(CN)(2). This anisotropy is caused by the molecular orbital angular momentum in the degenerate next highest occupied molecular orbitals of the molecular unit Fe(Pc)(CN)(2). Since the molecular unit Fe(Pc)(CN)(2) has a unique structure with fourfold symmetry, the molecular orbital angular momentum has a finite value of l(z) similar to +1 and -1. The anisotropic molecular magnetism of the unit Fe(Pc)(CN)(2) contributes the highly anisotropic Curie behavior. The molecular unit Fe(Pc)(CN)(2) is a good candidate for a molecular magnet having high magnetic anisotropy.

    Electrical resistivity under a high pressure and the upper critical magnetic field (H-c2) in the superconducting state were investigated on the ambient-pressure superconductor alpha-(EDT-TTF)[Ni(dmit)(2)], which exhibits a phase transition around 20 K and the superconducting transition at 1.3 K under ambient pressure. Above 9.9 kbar, the superconducting transition was not observed down to 0.5 K; while the former transition survived up to 13.7 kbar. The temperature dependence of H-c2 was estimated: \dH(c2)/dT\(T=Tc) approximate to -0.27 T/K (B parallel to c*-axis); \dH(c2)/dT\(T=Tc) approximate to -3.5 T/K (B parallel to ab-plane). The anisotropy of H-c2 within the ab-plane was found to be quite small indicating the two-dimensionally isotropic character within the ab-plane in the superconducting state of the salt.
