Abstract

3-(p-fluorophenyl), 3-(m-fluorophenyl) and 3-(m, p-difluorophenyl) thiophene were synthesized. The corresponding polymers were made by electropolymerization and characterized using cyclic voltammetry. The polymers exhibit reversible and stable p- and n- doping states and distinct color changes upon doping.

Keywords : Polythiophene; .Electrochemical polymerization; Electrochemical doping.
