点击化学在拓扑结构聚合物合成中的应用

APPLICATIONS OF "CLICK" CHEMISTRY IN SYNTHESIS OF TOPOLOGICAL POLYMERS

首先对点击化学进行简述,介绍了点击化学的概况、特征及主要反应类型;随后,重点介绍点击化学在拓扑结构聚合物(包括线形、刷形、星形、环状及树枝状大分子等)合成中的应用,并对这一领域的研究进展进行综述;最后,提出目前点击化学存在的一些问题,并对其发展前景进行展望.

＂Click＂ chemistry,proposed by Sharpless in 2001,has become a powerful and versatile synthetic tool because of some unique advantages, such as mild and simple reaction conditions, high efficiency and selectivity, and exceptional tolerance towards a wide range of functional groups and reaction conditions. In this review,the development of ＂click＂ chemistry （ e. g. , its history, characteristics and classifications） is firstly introduced. Subsequently,this paper focuses on the applications of ＂ click＂ chemistry in the synthesis of a variety of topological polymers, including linear, brush-shaped, star-like, cyclic polymers, and dendrimers. Finally,the limitations and prospects of ＂click＂ chemistry are also discussed.
