Research Abstract
This study aimed to construct spin crossover (SCO) and mixed valence (ET) complexes showing the external field-induced electronic state conversion. (1) SCO complexes with di-basic/acid ligands were synthesized, and it was shown that the protonation of the ligands could convert the spin state. (2) Cyanide ion-bridged mixed-valence complexes were synthesized. The complexes exhibited that the intermolecular ππ interactions produce stresses on the coordination structure, resulting in significant differences in the external field-induced phase transition temperature. (3) In two-dimensional SCO complexes, we realized a system in which the SCO and the dielectric response are coupled by the coupling between the SCO and the rotation of the pyrazole group in the bridging ligand.
