An optical study of the arsenic pentafluoride doping of poly(p-phenylene sulphide): polaron and bipolaron transitions

Abstract

The oxidative doping of thin films of poly(p-phenylene sulphide) by arsenic pentafluoride has been followed by transmission absorption spectroscopy (near i.r. to u.v.) and transitions are assigned involving cationic states, poloran and bipolaron, formed within the π–π* band gap.
