| Research Abstract |
We have investigated the mechanism of the excitation wavelength dependence of the photo-induced excited state intramolecular proton transfer reaction in ionic liquids, by using the ultrafast time-resolved fluorescence spectroscopy and the theoretical calculation on the electronic state including the solvation structure. We have revealed that the solvation heterogeneity induced by the alkyl-carbon of a cation molecule of ionic liquids enables the selective excitation of differently solvated molecules by the different excitation wavelength, which results in the selectivity of the chemical reaction by the excitation wavelength.
