Outline of Final Research Achievements

For expanding the availability of Cu(I) complexes as a redox photosensitizer, new stable Cu(I) complexes showing stronger visible-light-absorbing ability were synthesized. Utilization of a tetradentate ligand consisting of a 1,10-phenanthroline (phen) which tethers two phosphines through C4 alkyl chains at 2,9-positions stabilized the Cu(I) complexes. Introducing various substituents on 4,7-positions of phen showed red-shift of ca. 40 nm at maximum from the Cu(I) complex having non-substituted phen due to expansion of π-conjugation system of phen. The utilization of these Cu(I) complexes as a redox photosensitizer, an efficient photocatalytic system for CO2 reduction could be constructed.
