【 摘 要 】

In this work, it proposed thedeveloping of a new material, a modified electrode with metallic phthalocyaninesstacking columns, MxPc (Mx = Co, Fe and Ni), assembled by πinteractions, which have a behavior as a supramolecular system. These electrodesshowed an important electrocatalytic activity against nitrite oxidation, comparedto the same complexes monomer multilayers adsorbed on the electrode (M-MxPc).It is proposed two new obtaining methods of these systems, S1-MxPc, wherethe complexes would form a column and would be coordinated with the surfaceelectrode through a covalent bond of 4-aminopyridine (4-AP), and S2-MxPc,where the own functional groups of glassy carbon (GC) would be the covalentunions able to coordinate the complexes and the columns formation. These covalentunions between the electrode surface and phthalocyanines, would give a directionalstacking, and therefore, would modify both its electrocatalytical activity andits electrical features.
