Photogeneration of Polaron Pairs in Poly (Phenylene Vinylene)
Photoinduced absorption measurements of poly (phenylene vinylene), PPV, made picoseconds after above-gap photon excitation, have been interpreted as showing that a majority of the photons create polaron pairs bound by Coulomb attraction. We have calculated the peaks and approximate widths of the absorption bands due to a polaron pair on adjacent chains in PPV, and find good agreement with the observed absorption.
