dc.description.abstractIn this work, it proposed the developing of a new material, a modified electrode with metallic phthalocyanines stacking columns, MxPc (Mx = Co, Fe and Ni), assembled by p interactions, which have a behavior as a supramolecular system. These electrodes showed an important electrocatalytic activity against nitrite oxidation, compared to the same complexes monomer multilayers adsorbed on the electrode (M-MxPc). It is proposed two new obtaining methods of these systems, S1-MxPc, where the complexes would form a column and would be coordinated with the surface electrode through a covalent bond of 4-aminopyridine (4-AP), and S2-MxPc, where the own functional groups of glassy carbon (GC) would be the covalent unions able to coordinate the complexes and the columns formation. These covalent unions between the electrode surface and phthalocyanines, would give a directional stacking, and therefore, would modify both its electrocatalytical activity and its electrical features.
dc.description.abstractIt was also studied the dependence between the activity and the complex central metal (Co, Fe and Ni), finding a great dependence between them. It was found that the S2-MxPc modified electrodes were more stables and actives. The higher activity was found on S2-CoPc, which also performs a linear response. This last feature it is seen on a calibration curve with a large range of concentrations. It is important to notice that there is actually no relative information about the behavior of the new electrodes proposed on this work.
