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.
