Abstract

The preparation of poly(p-phenylenevinylene) and its derivatives has until now always involved a high temperature (200–300°C) conversion of the precursor polymer (see Figure) to the target polymer—a process that will cause problems in practical device fabrication. A room-temperature conversion method is described in which HBF4 simultaneously converts and dopes the chloride sulfonium precursor polymer to the metallic conducting form in one step.
