Summary Information provided by the agent in SIGEVA

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... 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.
