Highly Conducting Poly(P-Phenylene Vinylene) Prepared From Sulfonium Salt

Abstract
Highly conducting poly(p-phenylene vinylene), PPV, has been obtained via pyrolysis of the soluble precursor polymer derived from p-xylylene bis(diethyl sulfonium bromide) which is processed to film. The highly oriented PPV film is obtained by stretching the precursor film up to ten fold at a higher temperature. The films show extremely high conductivity of 2780 S/cm and 491 S/cm by doping AsF 5and SO3 respectivly, with high electrical anisotropy.
