Photochemical and Photophysical Behaviour of Phenylsilanes and Naphthylsilanes

The photochemical and photophysical properties of phenyl- and naphthylsilanes studied quantitatively.It was found that the photochemical reaction of naphthyldisilanes originates from the intramolecular charge-transfer state (2p?, 3d?) produced by 2p?*->3d? charge transfer.The rearrangement (Πr) and decrease (ΠR) quantum yields at 254 nm and the quantum yield (Πet) for the charge transfer emission for disilanylnaphthalenes decreased markedly with solvent polarity because of fast intersystem crossing (through the charge-transfer state) in competition with the radiative and reaction rates.Activation parameters for the photochemical reaction have been obtained.It is demonstrated that the substitution of a disilanyl group into a phenyl or naphthyl species strongly affects not only the photochemical reaction but also the photophysical processes containing fast intersystem crossing.
