[The UV-Vis spectrographic and electrochemical study on the beta-cyclodextrin inclusion compound of 3,3',5,5'-tetramethylbenzidine].
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.
