摘要：

采用同步循环伏安(CV)和电化学石英晶体微天平(EQCM)方法研究了冠醚(二苯并-18-冠-6)修饰的C60衍生物(DBCFP)固态膜在不同电解质的乙腈溶液中的电化学性质. 选择了连有刚性基团的C60衍生物PSF与DBCFP进行对比,提出了DBCFP膜在TBA+溶液中的反应机理.

Abstract:

The electrochemical properties of dibenzo-18-crown-6-C60(DBCFP) films were studied by simultaneous cyclic voltammetry and electrochemical quartz crystal microbalance(EQCM) in acetonitrile solutions containing different supporting electrolytes. The electrochemical properties and the stability of DBCFP film were much different from that of  C60 film due to the 18-crown-6 group with large size and soft property. For the sake of comparison,the electrochemical properties of another C60 derivative(PSF) with rigid perylene group were also investigated. A mechanism for electrochemical process of DBCFP film in TAB+ solution was proposed.
