| Outline of Final Research Achievements |
We aim to attain the photo-control of the proton transfer in molecular compounds. We achieved the light-induced proton transfer and the trapping of the light-induced excited proton transfer state using the proton-transfer coupled spin transition (PCST) mechanism for Fe(II) compounds through a precise molecular design. It should be noted that several molecular compounds, in which proton-transfer coupled electron transfer (PCET) is induced, have recently been synthesized. However, although spin and charge are two important aspects of electrons, no previous study has succeeded in demonstrating proton-transfer coupled spin transition (PCST) behavior in crystalline materials. The Fe(II) complexes are the first examples to display thermal and photoinduced PCST behavior.
