| Outline of Final Research Achievements |
This study aimed at construction of new photo-responsive molecule based on dipyrrinone, which is a scaffold of biological pigment, bilirubin. It was revealed that a newly synthesized dipyrrinone derivative bearing ethoxycarbonyl group at the pyrrolic position underwent high photoisomerization conversion. We also found that this molecule exhibited a solvent-dependent dual-mode photochromism between T- and P-types. While it underwent thermally reversible (T-type) photoresponsive reaction in chloroform, it became a thermally irreversible (P-type) system in methanol.
