Outline of Final Research Achievements

It was revealed that ring-shaped multi-nuclear rhenium(I) complexes exhibited efficient photosensitization as well as strong emission and multi-electron accumulation owing to the interligand aromatic interaction by changing the number of the nuclei and the modes of the linkage. In particular, the highest reaction quantum yield of photocatalytic CO2 reduction was achieved by using a ring-shaped multi-nuclear rhenium(I) complex as a photosensitizer, which showed the longest excitation lifetime. Moreover, other new tetrahedral copper(I) complexes involving aromatic interaction were obtained, but they did not show significant thermal stability and emission properties.
