The proposed research aims at developing crystals of spin crossover complexes with Light-Induced Excited Spin-State Trapping (LIESST) effect that exhibit photoinduced polarization change from ground state to excited state with long-lived metastable state. After we tried a series of 2,6-bis(pyrazol-1-yl)pyridine and bis[((2-methylimidazol-4-yl)methylidene)-3-aminopropyl]ethylenediamine derivatives as ligands to develop the Fe(II) spin crossover complexes, and we have obtained several polar Fe(II) spin crossover complex exhibited LIESST effect. However, the single crystals of the most of them are easy to cleavage after the spin transition, which does not facilitate the measuring of macroscopic polarization change of the compounds. Only one compound's single crystal remained intact after undergoing an incomplete spin transition. In this compound, 28% of Fe(II) changes from the low spin state of the ground state to the high spin state of the excited state after photoexcitation. The light-induced excited state with a relaxation time of 4609 s at 10 K will facilitate the test is sufficient to detect electric current in a crystal when it returns to the ground state. When the excited state returned to the ground state, a polarization change of ca. 0.45 μC cm－2 was detected. This study indicates that the combination of the LIESST effect and macroscopic polarization is a feasible way to realize photoinduced persistent polarization change.
