Synthesis and characterization of Lindqvist-type polyoxometalate–porphyrin copolymers
Résumé
Hybrid polyoxometalate-porphyrin copolymeric films were obtained by the electrooxidation of 5, 15-ditolyl porphyrin (H2T2P) and zinc-β-octaethylporphyrin (ZnOEP) in the presence of the Lindqvist-type polyoxovanadates TBA2[V6O13{(OCH2)3CNHCO(4-C5H4N)}2] (Py-POM-Py). The resulting films have been characterized by UV–visible absorption spectroscopy, X-ray photoelectron spectroscopy, atomic force microscopy and electrochemistry. Electrochemical quartz crystal microbalance was employed to investigate the copolymer mass.
