含环糊精链节的拓扑高分子

Cyclodextrin-Based Topological Macromolecules

星形、超支化、树枝状、刷状等具有支化拓扑结构的高分子通常具有不同于直链结构高分子的优异性能。将有客体包合功能的环糊精与其结合构筑环糊精拓扑高分子体系,有望在分子识别、基因传输、药控释放等领域得到应用。本文根据高分子拓扑形态的不同,从星形、超支化、树枝状以及其他拓扑形态环糊精聚合物的合成及自组装构筑等方面进行了总结和评述,并在此基础上展望了基于环糊精的拓扑高分子的研究方向和发展趋势。

Branched topological macromolecules, such as star-like, hyperbranched, dendritic and brush-like macromolecules, have many unique properties compared with their linear counterparts. Thus in recent years, when a combination of cyclodextrin （CD） possessing molecule cavities with topological structures is obtained, some important applications in various fields, such as molecular recognition, gene delivery and drug delivery system are endowed. In this article, the investigations and applications on the construction and self-assembly of cyclodextrin- based topological polymers are summarized according to the different topologies. The main content includes four aspects as following： （a） star-like cyclodextrin polymers, （b） hyperbranched cyclodextrin polymers, （c） dendritic cyclodextrin polymers, （d） cyclodextrin polymers with other topologies. In addition, new research trends are also expected based on the progress of this kind of polymer.
