Abstract
The time‐resolved fluorescence behavior of polystyrene and a series of styrene–methyl methacrylate copolymers has been examined by using pulsed laser excitation. Although the photophysical characteristics of styrene‐ and naphthalene‐containing polymers may be described by the same general kinetic scheme, some differences in the nature of the photophysical interactions are apparent. Umambiguous evidence for the occurrence of excimer dissociation into excited‐state monomer in polymers incorporating styrene chromophores is presented.
