Design of new electropolymerized polypyrrole films of polyfluorinated Zn(II) and Mn(III) porphyrins: Towards electrochemical sensors.
New Zn(II) and Mn(III) porphyrins functionalized by one and four electropolymerizable pyrrole groups resp. were synthesized and their electrochem. behavior was characterized in MeCN electrolyte. The electrooxidn. of these metallopolyfluoroporphyrins gave N-substituted polypyrrole films. The latter exhibit electrochem. behaviors identical to those of the corresponding monomers combined with the conventional electroactivity of the polypyrrole skeleton. Also, the potential electrocatalytic properties of Mn(III)-based polypyrrole films in the presence of mol. oxygen and benzoic anhydride were illustrated by cyclic voltammetry in org. soln. Preliminary expts. also demonstrated the potentialities of such polymeric films for the electrochem. detection of H2O2 in aq. media. [on SciFinder(R)]
