Abstract

A new triazine-derived cupric complex has been synthesized, and characterized to realize its spectroscopic and electrochemical properties. By introducing a side chain with amino-terminal, this complex can be immobilized onto carbon electrodes via the formation of a carbon-nitrogen bond using electrografting. The modified electrode showed electrocatalytic activity towards H2O2 reduction, and a better stability than the carbon ionic liquid electrode (CILE). A Fenton-like mechanism is involved in the H2O2 reduction, inducing the hydroxylation of coumarin to be hydroxycoumarin. This electrode shows the potential to be a H2O2 sensor and a hydroxylation electrode.
