| Outline of Final Research Achievements |
Solvatochromism and fluorescent solvatochromism are well-known phenomena in chemistry and biology, such as human color vision and fluorescent proteins. On the basis of our previous studies, we found essential roles of molecular environment that furnishes various functions via molecular interactions. In this study, we developed an wave-function-based method to efficiently describe the molecular interactions in the excited states. We also developed an analytical method to decompose the excited-state molecular interactions energies into polarization and dispersion effects. These approaches were applied for solvatochromic systems in solutions and clarified the origin of the spectral shift at the molecular resolution and at the physical-term resolution.
