FILMS OF POLY(PYRROLE-[RUII(BPY)2CL2]) - THEIR TRANSFORMATIONS INTO FILMS CONTAINING CIS-[RU11(BPY)2(H2O)2]2+ OR TRANS-[RUII(BPY)2(H2O)2]2+, [RUII(BPY)2(MECN)2]2+ AND [(RUIII(BPY)2(H2O))IO]4+ COMPLEXES, APPLICATION TO ELECTROCATALYSIS (BPY = 2,2'-BIPYRIDINE)

A ruthenium(II) bis(chloro) complex containing two 2,2'-bipyridine (bpy) ligands substituted with pyrrole groups has been synthesized and anodically electropolymerized on platinum, glassy carbon or SnO2 electrodes; [RuII(bpy)2Cl2] sites in the polymer are readily converted into other ruthenium complexes as cis- or trans-[Ru(bpy)2(H2O)2]2+, [{Ru(bpy)2(H2O)}2O]4+ and [Ru(bpy)2(MeCN)2]2+ and the capability of the polypyrrole cis-[Ru(bpy)2(H2O)2]2+ films to act as an electrocatalyst has been tested.
