SYNTHESIS, ELECTROCHEMICAL AND HETEROGENEOUS ELECTROCATALYTIC BEHAVIORS OF A NOVEL NON-SYMMETRICALCOPPER (II) COMPLEX

We describe in this paper the synthesis of new unsymmetrical tetradentate copper (II) Schiff base complex, prepared from tridentate Schiff base ligand (HL) and pyridine molecule. This new copper complex was identified by various physicochemical characteristics such as elemental analysis (EA), FT-IR, UV-Vis, XPS analysis and thermogravimetry (TG/DTG). The electrochemical behavior of the copper (II) complex was investigated by cyclic voltammetry in N, N-dimethylformamide (DMF). These experiments have been allowed to obtain new conducting polymeric films, prepared by successive cycling at the suitable potentials. These polymeric films containing metallic centers were studied to evaluate their electrocatalytical performances in which copper (II) ions were used as electrocatalysts in the heterogeneous conditions for the electroreduction of 1, 4-dibromobutane
