Abstract

Abstract: Photophysical and photochemical properties of phenyldisilanes having a trifluoromethyl substituent on a benzene ring as one of the most suitable substituents for stabilization of the OICT (us* orthogonal intramolecular charge transfer) state were investigated in detail. The OICT mechanism for CT fluorescence in nonpolar solvents was supported by the remarkable dependence of absorption and fluorescence spectra of ...
