| Outline of Final Research Achievements |
In this research, we tried to control the reaction selectivity by solvent ionic liquids which have a segregated structure composed of polar and non-polar domains from the view point of reaction coordinate and solvent coordinate. We clarified that the domain structure did not make a significant control of the reaction rate of the electron transfer reaction which is controlled by the long-ranged Coulomb force. On the other hand, photo-induced intramolecular proton transfer reaction is strongly affected by the domain structure and excitation wavelength of the reaction. The molecular dynamics of the non-polar domain was revealed not to have the relation with the solvent dynamics which affects the viscosity.

| Academic Significance and Societal Importance of the Research Achievements |
イオン液体のもつ構造特異性と反応基質の構造をデザインすることにより、化学反応の収率をコントロールできる可能性があることが本研究によって示され、またその物理化学的な背景があきらかとなった。特に、反応特異性が示される系とそうでない系の特徴を本研究で示したこと、また無極性部分の運動性の特徴が解明されたことは、今後イオン液体を活用していくにあたって、重要な指針をあたえるものと考えられる。
