前人已用极谱法研究过不同条件下单取代基二茂铁的电化学性质及一些双取代基二茂铁的电聚合膜,并讨论了有关的性质。本文用循环伏安法测定了一些双取代二茂铁(Ⅰ)的氧化还原电位,并讨论了它们与环上取代基的Hammett常数σ之间的依赖关系。从分子轨道理论计算对所得结果进行了满意的解释。
Polarographic methods have been used to study the electrochemical properties of monosubstituted ferrocenes under different conditions and some double-substituted ferrocene electropolymerized films, and discussed the nature. The redox potential of some disubstituted ferrocene (Ⅰ) was determined by cyclic voltammetry and their dependence on the Hammett constant σ of ring substituents was discussed. The results obtained from molecular orbital theory are satisfactorily explained.
