Photophysical and charge transfer studies of some model anthracene-backboned polyesters

K.R. Gorda; Ramesh Varadaraj; D. G. Peiffer; Cornelius Hendrick Brons

Abstract The preparation and characterization of several finely tailored anthracene-backboned polyesters are discussed. The anthracene fluorescence lifetimes (τ), fluorescence quenching kinetics ( k q ) and charge transfer equilibria ( K ct ) of the polymer-bound anthracene moieties (determined in chloroform) are also reported. Charge transfer complexation between the anthracene moiety and tetrachloro-1,4-benzoquinone (chloranil) is also investigated. In order to determine the extent of donor-acceptor equilibria, K ct are determined from Benesi-Hildebrand plots. These results are correlated to the overall effects of the aliphatic bridging group, which appear to influence the micropolarity and vibrational and rotational properties of the anthracene moiety.
