| Outline of Final Research Achievements |
We prepared and characterized Ru(IV)-oxo complexes to reveal their characteristics and reactivity in oxidation reactions of organic substrates. The reactions were revealed to proceed in a unique entropy-controlled mechanism involving adduct formation between Ru(IV)-oxo complexes and substrates. Based on the reactivity, we established highly efficient and highly selective photocatalytic oxidation systems of organic substrates in acidic water. On the other hand, a unique photocatalytic hydrogen evolution system has been developed using a Ru(II) complex having a π-expanded heteroaromatic ligand that acts as a reactive site. On the other hand, a Sc(III)-bound Pd(II)-porphyrin-flavin dyad was synthesized to achieve formation of a charge-separated state surviving for 0.11 s. In addition, photoinduced electron transfer was achieved from metal complexes to a diprotonated from of a new water-soluble saddle-distorted porphyrin.
