Oxidative doping of polyenes derived from chemically dehydrochlorinated poly(vinyl chloride)

Polyene sequences produced by chemical dehydrochlorination of poly(vinyl chloride) react with antimony pentachloride to form species with strong absorptions in the visible and near-infra-red regions of the spectrum, the detailed positions and relative intensities of which depend on the [polyene][SbCl5] ratio. The absorbances are discussed and compared with those described for related systems.
