Abstract

A new approach to the synthesis of polyrotaxanes from the polyethylenimine‒block‒poly(ethylene glycol)‒block‒polyethylenimine copolymer and alpha-cyclodextrin has been proposed. It has been shown that the acylation of free amino groups of polypseudorotaxane effectively blocks decomposition of the complex in solution. The structure of the synthesized copolymers has been studied in detail by ¹Н and ¹³С NMR spectroscopy, IR analysis, and GPC. It is assumed that the observed abnormally high optical activity of the resulting rotaxanes is probably associated with the formation of chiral helical supramolecular structures.

基于聚乙烯亚胺、聚乙二醇和 Alpha-Cyclodextrin 共聚物的新型聚异构烷烃

摘要提出了一种从聚乙烯亚胺-块状-聚（乙二醇）-块状-聚乙烯亚胺共聚物和α-环糊精合成聚假紫杉烷的新方法。研究表明，聚假紫杉烷游离氨基的酰化作用可有效阻止复合物在溶液中的分解。通过 1Н 和 13С NMR 光谱、红外分析和 GPC 对合成共聚物的结构进行了详细研究。据推测，所生成的轮烷之所以具有异常高的光学活性，可能与手性螺旋超分子结构的形成有关。
