Electrochemical oxidative polymerization of binuclear ‘anil’ and ‘salen’-type complexes and tetrahydro derivatives

Abstract

New kinds of modified electrodes have been prepared on the basis of electroactive polymers containing bimetallic ‘anil’ and ‘salen’-type complexes. New tetrahydro ‘anil’ ligands and complexes have been synthesized, giving birth to a new family of electroactive polymers. The polymers have been prepared potentiostatically and exhibit electrochemical properties analogous to simple polysalens. In the case of binuclear complexes both imino- and amino-linked monomers polymerize, but the polymers exhibit quite different charge transfer dynamics.

Les complexes binucle′aires posse′dant des liaisons imine et amine polyme′risent e′galement, mais les polymères pre′sentent des comportements très diffe′rents sur le plan du transfert e′lectronique.
