摘要：

The preparation of poly(pyrrole-metallotetraphenylporphyrin) films (metal = Ni(II), Zn(II), Co(II) and Cu(II)) has been achieved in CH2Cl2 +0.1 M Bu4NClO4 (TBAP) by anodic electropolymerization of the corresponding monomers in which the macrocycle is linked to a pyrrole group by an alkyl chain. The redox properties of these modified electrodes have been investigated by cyclic voltammetry. Their voltammograms display the regular electroactivity of the porphyrin derivatives; however, the reversible slow process Co(II)/Co(III) is exhibited only at a low sweep rate (nu = 0.005 V s-1). The free porphyrin base cannot be electropolymerized even in acidic conditions.
