Poly(benzimidazole) and substituted poly(benzimidazoles): Novel, electroactive, and conducting polymers possessing high catalytic and coordination properties

Benzimidazoles and substituted benzimidazoles were electropolymerized on a Pt electrode using acetonitrile containing 0.1 MNaClO4. The polymers are el ectroactive and conducting. They have a high electrocatalytic effect on the reduction of H+, O-2, and CO2 and exhibit high coordination ability. The p roperties of the polymers depend on the extent of conjugation in the monome r. (C) 2000 John Wiley & Sons, Inc.
