| dc.description | The macrocyclic ligand, tetraaminophthalocyanine, was electropolymerized on a glassy carbon electrode by continuously potentiodynamic scans, using two different solvents, dimethylsulfoxide and dimethylformamide. In the first case, an over-oxidation can takes place, which partially destroy the film and inhibits its electrocatalytic activity for the reduction of oxygen compared to the polymer grown in dimethylformamide. To avoid this over-oxidation, two possible ways can be used: to achieve the electropolymerization during a lower number of potentiodynamic scans or using a positive potential limit shifted to more negative potentials. If a narrow potential interval is used, the electrocatalytic behavior of the polymer is similar to that obtained in dimethylformamide. However, if a wide potential interval is used but only during few potentiodynamic scans, it is possible to obtain a polymer with a new redox signal that presents a very interesting electrocatalytic activity for the reduction of molecular oxygen | |
