Abstract

Two new ruthenium-poly(terthiophene) complexes substituted with di-phosphines, PTA (1,3,5-triaza-7-phosphaadamantane) and mPTA (N-methyl-1,3,5-triaza-7-phosphaadamantane), have been chemically synthesized and characterized by multinuclear NMR spectroscopy (1H, 13C and 31P), FT-IR, elemental analysis, UV-Vis and cyclic voltammetry. The latter technique allowed the electro-polymerization of the two novel complexes upon Pt disk electrodes, generating thin films whose electrochemical response could project their utility in important applications such as batteries (reversible p-doping/undoping response in the range between -0.3 and 0.7 V vs SCE) or analytical sensors (response as a reversible redox couple between -0.3 and -1.0 V vs SCE).
