Fluorescence quenching and singlet energy migration in polystyrene and its copolymers
A study of fluorescence quenching of polystyrene and statistic styrene copolymers with methyl methacrylate, ethyl acrylate and acrylonitrile by carbon tetrachloride in 1,2-dichloroethane has been carried out. The results of the study have been interpreted on the basis of the modified Stern-Volmer relation, which takes into account the fact that isolated styrenes do not participate in the process of energy migration. The coefficients of energy migration were determined for the systems studied. It was shown that the intramolecular excimers restrict the process of energy migration in polystyrene and its copolymers. The results obtained are discussed.
