An original copper-phenolate complex, mimicking the active center of galactose oxidase, featuring a pyrene group was synthesized. Supramolecular pi-stacking allows its efficient and soft immobilization at the surface of a Multi-Walled Carbon Nanotube (MWCNT) electrode. This MWCNT-supported galactose oxidase model exhibits a 4 H(+)/4 e(-) electrocatalytic activity towards oxygen reduction at a redox potential of 0.60 V vs. RHE at pH 5.
合成了一种模拟半乳糖氧化酶活性中心的含芘基的新型铜-酚配合物。超分子π-堆积作用可使该配合物高效且柔和地固定在多壁碳纳米管（MWCNT）电极表面。这种 MWCNT 负载的半乳糖氧化酶模型在 pH=5 时，其还原氧的氧化还原电位为 0.60V 相对于 RHE 下，表现出 4H(+)/4e(-)的电催化活性。
