| Outline of Final Research Achievements |
The demand for clean energy sources, such as hydrogen (H2) produced from water and solar energy, has increased in recent years. In this context, the goal of this research was to construct a new photochemical H2-generating system based on ion-pairing of iridium(Ir) photosensitizers with molecular catalysts in lipid bilayer membranes where efficient photoinduced electron-transfer could occur between these components. We have developed new cationic and anionic Ir complexes with coumarin dyes and found that these complexes work as photosensitizers in visible light-driven H2 generation. Some cationic Ir complexes have been successfully incorporated into bilayer membranes of vesicles. We have also synthesized a new “soft salt” that is composed of a cationic Ir complex and anionic cobalt molecular catalyst.
