Outline of Final Research Achievements

As for the introduction of the asymmetry into the axial ligands, only a charge transfer salt composed of Fe(pc)(CN)Cl showed dielectric relaxation. This suggests the introduction of the asymmetry is effective method for this study, however, that into the axial ligands is not enough to induce clear inhomogeneity in the system.
Then, asymmetric Pc ligand, adjacent two of four benzene rings were substituted, was tried. To investigate the effect of the substitution into the cyclic ligand on the electrical and magnetic characteristics, a charge transfer salt consisting of tbp, whose molecular structure is quite similar to Pc, was also fabricated.
