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.

通过电接枝固定在碳电极上的新的三嗪衍生的铜配合物的表征,显示出对过氧化氢的电催化活性
合成了一种新的三嗪衍生的铜配合物,并对其进行了表征,以实现其光谱学和电化学性质。通过引入具有氨基末端的侧链,可以使用电接枝通过形成碳氮键将这种络合物固定在碳电极上。改性电极显示出对H 2 O 2还原的电催化活性,并且比碳离子液体电极(CILE)具有更好的稳定性。H 2 O 2还原涉及芬顿样机制,诱导香豆素羟基化为羟基香豆素。该电极显示出可能是H 2 O 2传感器和羟基化电极。
