Electrochemical Synthesis & Studies of Conducting Poly Quinoline

Abstract

The electrochemical polymerization of quinoline has been studied in acetonitrile medium using tetra-n-butyl ammonium perchlorate (TBAPC), tetraethylammonium perchlorate (TEAPC), tetraethylammonium fluoroborate (TEAFB) electrolytes. The polymer produced showed conductivity in the range of 10^–6 to 10^–1 Ω^–1 cm^–1 using the four probe technique. Polyquinoline was obtained in moderate yields with the highest Rp of 5.1354% per hr and polymerization efficiency of 51.698 mol/Faraday. The observations and experimental results suggested a free radical mechanism.
