Synthesis of Electric Conductive Poly(2,5-Pyrrolylene Vinylene) (PPRV)

Abstract

Poly(2,5-pyrrolylenevinylene)(PPRV) was obtained from the monomer, 2, 5-bis(methylenedimethylsulfoniumchloride) pyrrole, which was prepared from 2,5-dimethylpyrrole by the modified sulfonium polyelectrolyte precursor route. The polymerization conditions for the preparation of precursor polymers were examined. The highest yield was obtained when the precursor polymer, poly(α-methoxy-2,5-pyrrolylene) [poly(α-MeO-PRY)], was synthesized at -40°C with the monomer/base concentration ratios of 0.5/0.2. PPRV obtained by the thermal elimination of the precursor polymer at 220°C exhibited highest electrical conductivity, being the order of 6.9 × 10⁷ Scm⁻¹.
