用循环伏安法在二氯甲烷、二氯乙烷、乙腈、丙酮,苯腈、吡啶、二甲基甲酰胺、二甲基亚砜等不同溶剂中,研究了稀土穴醚配合物Eu(NO_3)_3(2,2)和Eu_2(NO_3)_6(2,2,2)的电化学行为。测定了其氧化还原反应的半波电位及电子转移速度常数,讨论了E(1/2)、k_s与溶剂及支持电解质的关系。
Cyclic voltammetry in dilute dichloromethane, dichloroethane, acetonitrile, acetone, benzonitrile, pyridine, dimethylformamide, dimethyl sulfoxide and other different solvents, the study of the rare earth Cryptophane complex Eu (NO_3 ) _3 (2,2) and Eu_2 (NO_3) _6 (2,2,2). The half-wave potentials and electron transfer rate constants of the redox reaction were measured. The relationship between E (1/2), k_s and solvent and supporting electrolyte was discussed.
