Resumen:
Sequential electropolymerization of aniline followed by an aniline
derivative bearing an ion moiety is presented. The studied derivatives
contain sulfonic, carboxylate or amino groups. Its electrochemical
behavior at acid and neutral pH is studied by cyclic voltammetry
combined with quartz crystal microbalance or probe beam deflection in
order to assess the mass transfer process involved in these new modified
electrodes. All of them show a stable and quasi-reversible
electrochemical behavior at neutral pH that can be attributed to a
self-doping process. These new modified electrodes can be further
modified due to the presence of functional groups
