| Outline of Final Research Achievements |
This research was aiming to realize a new photo-responsive system by combining a photo-induced electron transfer, proton transfer, and conformational change. A newly designed compound consisting of anthranol and acridine was synthesized and its photo-induced-electron transfer was confirmed. However, it was revealed that the reducing ability of the acridine unit after electron transfer was so high that side reactions with solvent molecules prevailed. In addition, an isomerization with a large structural change, which is a part of the initially targeted multistep reaction, was achieved. In particular, a new function in which the molecular structure responds to solvent polarity was realized by the difference in the zwitterionic character of the two isomers.
