摘要: 采用循环伏安法研究了二茂铁(Fc)在几种离子液体中的迁移行为. 计算了Fc在各离子液体中的扩散系数和粘度系数,探讨了离子液体粘度与离子液体结构之间的关系. 实验结果表明, 离子液体的粘度随阳离子取代基碳链长度的增加而增加, 随阴离子对称性的增加而增加.

关键词: 离子液体, 二茂铁, 循环伏安法, 粘度系数

Abstract: The transfer behavior of ferrocene(Fc) in various ionic liquids was investigated with cyclic voltammetry, and the diffusion coefficients of Fc in various ionic liquids and the viscosity of ionic liquids were estimated in this paper. In addition, we also discussed the relationship between viscosities and structures of ionic liquids. Our experimental results demonstrated that the viscosities of ionic liquids increase with increasing the alkyl chain length of cation and symmetry of anion structure of ionic liquids.

Key words: Ionic liquid, Ferrocene, Cyclic voltammetry, Viscosity coefficient
