The surface-initiated electropolymerization of pyrrole on functionalized platinum and glassy carbon surface is described in this work. The electrode surface was modified by electrochemical reduction of pyrrole-substituted benzenediazonium salt synthesized from the corresponding nitroaniline molecule. Such process resulted in the organic monolayer covalently bound to the surface, that due to its structural conjugation, could act as the initiator for the electropolymerization of pyrrole. The obtained layers were investigated by means of electrochemical and spectroscopic methods.
