The Eu(Ⅲ) with 25,27-dibenzyloxy-5,11,17,23-tetra-tert-butyl-26,28-dihydroxycalix[4]-arene film electrode(Eu(Ⅲ)-Calix-2Ar/GC) was firstly prepared. Cyclic voltammetric experiments showed that, in NaClO_4 solution, the film electrode has one pair of well defined and relatively stable reduction and oxidation peak. For this pair of peak, E_pc=-0.69 V and E_pa= -0 47 V(vs. SCE). Various factors which affect the voltammetry of Eu(Ⅲ)-Calix-2Ar film electrode and the charge transport process of the electrode are discussed. Research showed that the voltammetry of the film electrode is affected by the concentration of supporting electrolyte ,the film thickness, solvent and the film has some properties of supramolecular system.
