Post-Polymerization Electrochemical Functionalization of a Conducting Polymer: Diazonium Salt Electroreduction at Polypyrrole Electrodes

In this paper we report the functionalization of conductive polypyrrole (PPY) films via electrochemical reduction of the aryl di-azonium salts in a manner that is similar to the one employed for other conductive surfaces. To understand the general trendsof the grafting behavior of diazonium salts and to establish the optimal conditions for the covalent functionalization of the PPYfilms, we have compared the grafting behavior of four
