Abstract
Abstract Combining the measurement of fluorescence yield and decay-time as a function of temperature, the activation energies and frequency factors corresponding to several photophysical processes have been determined for solutions of poly-1-vinylnaphthalene and its copolymers with methylmethacrylate. The results are discussed in relation to copolymer composition and compared with those reported in the literature for model compounds. Excimer dissociation is found to be unimportant in the polymeric systems. This is tentatively assigned to a lower value of the frequency factor corresponding to excimer dissociation.
