The influence of a silica (aerosil) surface on the reaction kinetics of a photoinduced electron transfer and quenching of fluoresence of pyrene (Py) in the presence of N,N-dimethylaniline (DMA) when adsorbed from hexane has been studied. A photoreaction between Py and DMA is observed; over a wide range the quenching of the Py fluorescence obeys a Stern-Volmer equation mainly. When Py and DMA are solubilized in aqueous micelles of TX-100 and then adsorbed on an aerosil surface, the influence of the surface on the photoreaction kinetics is negligible. Removal of water from the above system leads to the suppression of the photoreaction. The apparently abnormally long lifetime of Py may be explained by a rearrangement of an adsorption layer, micelle degradation, and encapsulation of the fluorophore.
