Electrochemical polymerization of benzene in the presence of Ag⁺, Pb²⁺ and Cu⁺ ions

Abstract

Poly(p-phenylene) (PPP) films were synthesized by using benzene and fluorosulphonic acid (FSO₃H) as a strong acid containing Ag₊, Pb₂₊ and Cu₊ ions in methylene chloride (CH₂Cl₂) solution. Addition of Ag₊ or Pb₂₊ ions into the polymerization medium improved the PPP films formation, but Cu₊ ion did not have an effect on polymerization. PPP films were characterized by cyclic voltammetry, IR and TGA. Dry conductivities were measured by using four probe technique.
