The anodic electropolymerization of thiophene-functionalized cyclometalated ruthenium(II) complexes is shown for the first time. It is demonstrated that the electron-rich complexes tolerate the highly positive potentials that are required for the thiophene oxidation if electron-withdrawing groups are installed at the cyclometalating phenyl ring. Thus, conductive polymer films featuring a broad UV-vis absorption as well as reversible redox-switchability can be prepared. The employed cyclometalated ruthenium(II) complexes are promising candidates for future photovoltaic applications based on photo-redox-active films.
