Abstract
Abstract The binuclear [ Ru ( bpy ) ( CO ) 2 ( CH 3 CN ) ] 2 2 + (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 two-electron reduction process. The resulting molecular cathodes are highly efficient electrocatalysts for the selective reduction of CO 2 in pure aqueous media. In this paper, the simple in situ synthesis and the electrochemical behavior of a series of binuclear complexes [ Ru ( L ) ( CO ) 2 ( CH 3 CN ) ] 2 2 + (L = bipyridyl ligands substituted by one or more pyrrole groups) are reported. In addition, to generating [Ru(L)(CO) 2 ] n electropolymerization, anodic oxidation of the complexes allow the formation of functionalized polypyrrole films. The electrochemical properties of these films towards CO 2 reduction have been also investigated.
