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. Electropolyme′risation anodique de complexes binucle′aires de type ‘anil’ et ‘salen’ et de leur de′rive′s tetrahydroge′ne′s. Un nouveau type d'e′lectrodes modifie′es a e′te′ e′labore′ sur la base de polymères e′lectroactifs issus de complexes bime′talliques de type ‘anil’ et ‘salen’. Nous avons synthe′tise′ des ligands et complexes tetrahydro ‘anil’ originaux donnant accès à une nouvelle famille de polymères e′lectroactifs. 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.
