| Outline of Final Research Achievements |
In this study, novel functional molecules utilizing the photoinduced charge separation were developed for a fundamental technology to develope photocontrol methods of cellular activities. We investigated intracellular optical functionality mainly for amphipathic ferrocene-porphyrin-fullerene linked molecules and aryl-acridinium molecules.
As research outcomes, we succeeded in photoinduced depolarization of the cell membrane by high charge separation efficiency due to development of molecules with enhanced cell membrane fluidity. In addition, we succeeded in mitochondria selective molecular transport in living cells by utilization of drug transport carriers or optimization of molecular structure. The molecules demonstrated successful method for triggering photooxidation/reduction reactions in cells by irradiation with light.
