| Outline of Annual Research Achievements |
The proposed research aims at developing molecular crystals with photo-induced macroscopic polarization change with current output during the relaxation process from excited state to the ground state. We focused on the spin crossover complexes with Light-Induced Excited Spin-State Trapping effect and Prussian blue analogues with photo-induced electron-transfer-coupled spin transition process. We have obtained a polar Fe(II) spin crossover complex and a trinuclear [Fe2Co] Prussian blue analogue with photo-response. During relaxation process, the output current was observed as expected. This study will benefit the development of multifunctional optoelectronic materials and energy conversion materials.
