Electrochemical preparation of conductive films of tetrapyridylporphyrins coordinated to four [Ru(5-NO2-phen)(2)Cl](+) groups

Artículo de publicación ISIThis work describes the preparation of a new tetraruthenated porphyrin and the corresponding polymeric film. This macromolecule consists of a Ni(II) tetrapyridylporphyrin coordinated to four [Ru(5- NO2-phen)2Cl]+ moieties. The 5-NO2-phen ligands are reduced at 0.90 V, generating a radical anion that is able to generate polymeric coatings onto glassy carbon (GC) electrodes. These polymeric films are very stable in aqueous solutions. The polymeric films are characterized by electrochemistry, infrared spectroelectrochemistry (IR-SEC) and atomic force microscopy (AFM).The authors acknowledge: the financial support of Programa Bicentenario en Ciencia y Tecnología, CONICYT-Banco Mundial, Anillo ACT-24 Project, Fundación Andes C14060-40 Project and UTA-4741-10 Project.
