| Outline of Final Research Achievements |
To develop a new methodology to control of photo-excitation energy dynamics in the mesoscopic region, we have investigated the effect of meso-crystallization on the photoluminescence properties of coordination polymers (CPs), and the effect of surface modification of semiconductor nanoparticles on the photosensitization ability. We found that meso-crystallized CP exhibited different luminescence behavior from that of bulk crystals and molecular complexes. In the solar water splitting reaction driven by semiconductor nanoparticles, we found that the ligand covering the surface of the photosensitizing nanoparticle was involved in the formation of the catalyst-photosensitizer complex. In addition, we demonstrate that the efficiency of the interfacial electron transfer reaction on the dye-semiconductor interface was drastically improved by the formation of multilayers of sensitizing dyes. These results indicate the importance of the nanostructure in the photo-generated exciton dynamics.
