Outline of Final Research Achievements

In this research, we attempted to prepare two-photon absorption switching system based on redox reaction. To achieve this, we focused on quinoidal molecules and prepared those with redox units. Specifically, dicyanomethylenated quinacridone and diarylmethylene substituted thiophene derivatives were prepared and their redox, photophysical properties were examined. During the course of this project, we found some crystal jumping behavior, which mechanism was also examined.
