| Outline of Final Research Achievements |
In this research, we develop a new field of chemistry, asymmetry chemistry, by fabricating the asymmetric structures composed of various inorganic nanocrystals. An anisotropic assembly of near-infrared plasmonic nanocrystals and carrier acceptor nanocrystals was successfully achieved while controlling their band positions. Then we achieved high quantum yield and charge separation lifetime exceeding microseconds in near-infrared light-induced directional charge separation by utilizing trap levels etc. of plasmonic nanocrystals. We also succeeded in synthesizing pseudo-tetrahedral Au nanocrystals planarly coordinated with four porphyrin derivatives, and demonstrated that the electrochemical hydrogen evolution reaction activity is enhanced by the charge transfer from porphyrin to the Au core.
