| Abstract: | The covalent modification of glassy carbon electrodes by oxidation of unsaturated aliphatic carboxylates is reported in this work. It is shown that the presence of π-bonds on the hydrocarbon structure is essential to develop the grafting process, which does not occurs with totally saturated carboxylates. In this way, the glassy carbon surface modification with aliphatic chains containing alkene and alkyne groups was performed and the presence of such groups was demonstrated through a Heck and a Click reaction, allowing respectively a further functionalization with nitrobenzene and ferrocene groups. |
