Abstract

The rate of incoherent electronic excitation transport among chromophores randomly tagged on flexible polymer chains has been related theoretically to their ensemble average rms radius of gyration (<¹R 2>1/2). The rate of excitation transport is monitored by time-resolved fluorescence depolarization spectroscopy. Experiments which measure the rate of excitation transport among naphthyl chromophores in low concentration on iso-lated chains of poly-(2-vinylnaphthalene-co-methyl methacrylate) in poly(methyl methacry-late) (PMMA) host provide a quantitative determination of the copolymer <R 2>1/2. Measure-ments were made on copolymers of two different molecular weights and three different percentages of naphthyl containing monomers. In all cases, the measured <R 2>1/2 agree with determinations by other methods for PMMA in 6-solvents and are independent of 2-vinylnaphthalene concentration. The results demonstrate the utility of excitation trans-port techniques for quantitative investigation of polymer chain conformation in the solid state.
