Grafting of the gold surface by heterocyclic moieties derived through electrochemical oxidation of amino triazole - an experimental and "" study.

Surface modification of gold is accomplished by using the aminyl radicals formed through the electrochemical oxidation of the amino-triazole molecule dissolved in organic media (acetonitrile). The electrochemistry of the grafting process and the redox behavior of the grafted heterocyclic layer are similar to those of aliphatic amines. The presence of AT groups on the electrode surface was studied by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) before and after the functionalization process to confirm and prove the formation of a layer on the surface.

Experimental and Theoretical Study of the Covalent Grafting of Triazole Layer onto the Gold Surface.

Finding novel strategies for surface modification is of great interest in electrochemistry and material sciences. In this study, we present a strategy for modification of a gold electrode through covalent attachment of triazole (TA) groups. Triazole groups were electrochemically grafted at the surface of the electrode by a reduction of in situ generated triazolediazonium cations.
