Abstract
The optoelectronic properties of dilute solutions of oligomeric and (broken-conjugation) polymeric phenylenevinylene chains were studied using the following techniques: optical absorption and (time-resolved) emission spectrophotometry, flash-photolysis time-resolved (real and imaginary) microwave conductivity, pulse-radiolysis time-resolved microwave conductivity, and pulse-radiolysis time-resolved optical absorption spectrophotometry. The following properties were determined: absorption and emission spectra, fluorescence quantum yields and decay times, exciton polarizabilities and dissociation probabilities, charge mobilities, and radical cation absorption spectra. The experimental results are compared with theoretical calculations of exciton polarizabilities, charge mobilities, and radical cation absorption spectra.
