| Outline of Final Research Achievements |
Substituent effects of the ruthenium complexes have been investigated on the photocatalytic CO2 reduction. The positions of methyl groups introduced in the bipyridyl ligand of the ruthenium complexes affect the catalytic activities. The effects have been discussed in terms of back electron transfer from the catalyst to the photosensitizer. In this work, the functionalization of the metal complexes by utilizing the peptides containing unnatural bipyridyl amino acid has also been assessed. Specifically, the ruthenium dinuclear complex linked with a peptide has been newly synthesized, and the photocatalytic CO2 reduction is found to show the different product selectivity from that by the mononuclear complex.
