摘要

We describe here an original electrochemical proceeding for elaboration of a new kind of redox active molecular wires based on metal-metal bonded chains having the generic formula [M~0(L)(CO)_2]_n (L = 2,2'-bipyridine or 1,10-phenanthroline derivatives; M = Ru or Os. These molecular materials displays outstanding electrocatalytic activity toward reduction of carbon dioxide and can be easily prepared as thin films on conductive materials by electroreduction of a mononuclear (e.g. [M~Ⅱ(L)(CO)_2Cl_2]) or a binuclear (e.g. [M~Ⅰ_2(L)_2(CO)_4Cl_2]) complex precursor. The overall process involves the addition of two electrons per complex associated with the loss of two labile ligands like Cl~-. It has been demonstrated that polymerization occurs by an electrochemical propagation process. Characterization of the [M(L)(CO)_2]_n polymeric molecular wires has been made using various physico-chemical techniques.
