| Outline of Final Research Achievements |
I have studied surface nanostructures of organic compounds on inorganic semiconductors and their functions using various inorganic semiconductor nanoparticles and organic compounds in a wide range from a strong adsorption regime (chemisorption) to a weak adsorption regime (physisorption). I found that bisphenol derivatives form nanocavity structures on TiO2 surfaces in a strong adsorption regime. The cavity nanostructures feature the photoinduced charge change due to interfacial charge-transfer transitions. In a weak adsorption regime, methylene blue forms H-aggregates on SrTiO3 surfaces due to photoinduced diffusion motion. The photoinduced molecular transfer occurs by one-cycle charge-distribution change in methylene blue due to electronic excitation and relaxation. These results provide new knowledge for the construction of surface nanostructures.
