(C_(70))_2-对叔丁基杯[8]芳烃化学修饰电极在V（乙腈）：V（水）＝2：3混 合溶剂中，发生两步还原／再氧化反应，分别对应于两电子和四电子转移。用扫描 电子显微镜和光电子能谱对修饰电极进行了表征。循环伏安实验表明，(C_(70)) _2-对叔丁基杯[8]芳烃的两步还原过程均匀卤代酸的还原具有电催化作用。

The (C_(70))_2-p-tert-butylcalix [8] arene chemically modified electrode had two couples of redox reactions in mixed solvents of MeCN and water (2:3, volume fraction), corresponded to two-and four- electron transfer, respectively. The modified electrode was characterized by the scanning electron microscope and X-ray photoelectron spectroscopy. Both the reduction steps of (C_(70))_2-p- tert-butylcalix [8] arene exhibited catalytic activity towards the reduction of halogenated acid.
