Electrochemical behavior of binuclear [Ru(L)(CO)2(CH3CN)]22+ complexes (L = 2,2'-bipyridine substituted by pyrrole groups). Their reductive and oxidative electropolymerization.
The binuclear [Ru(bpy)(CO)2(CH3CN)]22+ (bpy = 2,2'-bipyridine) complex is an excellent precursor for the formation of redox polymeric Ru-Ru bonded films [Ru(bpy)(CO)2]n on electroactive surfaces by a 2-electron redn. process. The resulting mol. cathodes are highly efficient electrocatalysts for the selective redn. of CO2 in pure aq. media. The simple in situ synthesis and the electrochem. behavior of binuclear [Ru(L)(CO)2(CH3CN)]22+ (L = bipyridyl ligands substituted by ≥1 pyrrole groups) are reported. To generating [Ru(L)(CO)2]n electropolymn., anodic oxidn. of the complexes gave functionalized polypyrrole films. The electrochem. properties of these films towards CO2 redn. were also studied.
