Abstract

Abstract: The hydrolysis of titanium complexes has seriously limited their applications. Their hydrolytic characteristic was closely related to the antitumor activity. Therefore,it was necessary to use proper testing methods to evaluate the hydrolytic behavior of titanium complexes. This article introduced a series of methods for investigating the hydrolysis of titanium complexes,including UV-Vis,¹H NMR,X-ray crystallography,potentiometric analysis,conductivity method,and quantum chemistry computations. The strength and shortcomings of those methods were analyzed and compared. It was also described that the methods contributed to the investigations on the hydrolytic kinetic of titanium complexes,which could promote the progress of titanium complexes on medical and chemical industry.

Key words: complexes, hydrolysis, UV-Vis, nuclear magnetic resonance (NMR), X-ray crystallography, electrochemistry, electrolysis, computational chemistry

摘要： 由于茂钛配合物的易水解性严重影响其催化活性,而且其水解特点与抗肿瘤活性紧密相关,因此需要采用合适的检测手段来评价其水解行为。本文介绍了一系列检测茂钛配合物水解的研究手段——UV-Vis、¹H NMR、X射线晶体学、电位分析法、电导法、量子化学计算方法,分析了各种测试方法适用的范围及优缺点。提出这些测试方法有助于研究茂钛配合物的水解动力学,能够促进茂钛配合物在医学及化工方面的研究与进展。
