Several polyalkylviologen electrolyte complexes were prepared and used as electrontransfer catalysts(ETC) for the reduction of azobenzene in heterophase condition [reductant: Na~2S~2O~4(in H~2O)-polyalkylviologen complex (solid)- azobenzene (in CH~2Cl~2) ]. The results show that the polyalkylviologen-polyanion complex has the ability to induce the reduction of azobenzene and different polyelectrolyte complexes have different electron-mediating ability.
