| 摘 要： | 本文采用紫外－可见光谱和电化学的方法研究了３，３’，５，５’－四甲基联苯胺（ＴＭＢ）和β－环糊精形成超分子包合物后的氧化还原性质，研究结果表明在形成包合物后ＴＭＢ的氧化还原特性更好，尤其是在有酶参与时更易被氧化。在包合物内的氧化产物组分更单纯，修饰在电极表面也表现出更好的氧化还原活性。

| Abstract: | This paper reports the results of UV-Vis spectrographic and electrochemical studying on the beta-cyclodextrin inclusion compound of 3,3',5,5'-tetramethylbenzidine (TMB). The molecules of TMB show better redox performance after they were included in the cavities of beta-cyclodextrin, especially while there were the redox enzyme. The composition of oxidization product in the inclusion compound is more single. The results were also revealed by the obviously increasing of voltammetrical current when this inclusion compound was modified on the electrode surface. It is reasonable to conclude that the formation of TMB-beta-cyclodextrin inclusion compound would enhance the sensitivity of those analytical methods based on the redox reaction of TMB. |
