Electrochemical Synthesis of o-anisidine - o-aminophenol ?Copolymers

Abstract

Electroactive conducting copolymers of o-anisidine and o-aminophenol molecules were pre-?pared in ?aqueous solution by electrode ?potential cycling. Copolymerization was carried out at ?constant feed ?concentration of o-anisidine (30 mM) and different feed concentration of o-?aminophenol on a ?gold ?electrode. Three different feed concentrations of o-aminophenol were ?used to prepare three different ?copolymers. The ?obtained copolymers were characterized with ?cyclic voltammetry. ?Both homopolymers ?and copolymers were obtained by cycling the potential between -0.20 V and different upper ?potential ?limits.? The copolymers formed with different feed concentrations of o-aminophenol exhibited different ?cyclic ?voltammetric behav?iors. In some cases using different cycling range of polymerization leads ?to ?different cyclic ?voltammetric behaviors of the obtained copolymers.?
