Abstract
The photoluminescence characteristics of 2-vinylnaphthalene–styrene copolymers were studied under photostationary and transient conditions. Kinetic analysis of the monomer and the excimer emission was carried out, where the migration rate of excitation energy kt and the excimer formation rate of an adjacent pair of naphthalene units on the copolymer chain k21 were treated. Observed decay curves and quantum yields were in agreement with those calculated by the kinetic equations, and the rate constants were obtained: kt=3×108 s−1, k21=2×108 s−1. The results indicate that the fast migration of excitation energy brings about the quenching of the excited monomer state, and causes the efficient intramolecular excimer formation.
