摘要：
Functionalized polypyrrole films containing M-1(L)(diene)](+) complexes (M = rhodium or iridium, L = substituted 2,2'-bipyridine or 1,10-phenanthroline) have been synthesized by complexation of [M-1(diene)CL](2) precursor complexes in polyL films pre-coated on carbon and platinum surfaces by oxidative electropolymerization of pyrrole-substituted polypyridyl ligands, and characterized by cyclic voltammetry and X-ray photoelectron spectroscopy, The efficiency of the in situ complexation reaction appears strongly dependent on the permeability of the ligand film. The electrochemical behaviour in aqueous electrolyte and the electrocatalytic activity of these metallopolymers towards water reduction and hydrogenation of unsaturated organic substates is described.
