Abstract

Poly(4,4′-diphenylenediphenylvinylene), PDPV, is a soluble conjugated polymer that shows a degree of conjugation similar to that in poly-(paraphenylene). The optical properties of thin films exposed to AsF5 show the appearance of features below the π-π* gap at 3 eV that can be interpreted in a model of dopant-induced polaron and bipolaron defects. When excited above the π-π* gap, PDPV shows a strong luminescence peaked at 2.4 eV. The Stokes' shift of 1 eV can be accounted for by radiative decay from a photogenerated polaron-exciton defect.
