Outline of Final Research Achievements

Water photolysis consists of five processes: (a) light harvesting, (b) photoinduced charge separation, (c) hydrogen generation, and (d) oxygen generation. Under the theme of without using noble metals, we investigated light energy conversion systems. Initially planned supramolecules as an integrated system of (b) and (c) were unable to produced hydrogen. Concerning (a), we found that synthetic chlorophylls assemble into ordered molecular architectures. In relation to (b), naphthalimide and perylenimide derivatives were developed as dyes with high photodurability and dyes for dye-sensitized solar cells. Concerning (c), we obtained electrocatalysis from a mixture of acetylacetone dioxime and divalent copper ions.
