摘　　要：Compared to traditional polymer hydrogels,supramolecular hydrogels exhibits superior reversibility and stimulus response due to the instantaneous and reversible nature of non-covalent bonds.In this paper,we utilized the host-guest exclusion interaction between Decamethylcucurbit[5]uril(Me_(10)Q[5])and the 2,7-diaminofluorenedihydrochloride(DAF·HCl)to construct a Q[n]-based hydrogel system.The composition,structure,and properties of the hydrogel were compre-hensively characterized using rheometer,nuclear magnetic resonance,scanning electron microscope.This cost-effective and straightforward hydrogel synthesis method paves the way for the scalable production of practical and commercially viable Q[n]-based hydrogels.超分子水凝胶由于非共价键的瞬时和可逆性,与传统聚合物凝胶相比,具有良好的可逆性和刺激响应性。利用Me_(10)Q[5]与2,7-二氨基芴二盐酸盐之间的端口作用构筑了瓜环基水凝胶体系,采用流变仪、核磁共振、扫描电镜等多种方法研究了水凝胶的组成、结构和性能。结果显示:这种易于合成,低成本的水凝胶制备方法有利于后续制备更实用、更具有市场可行性的瓜环基水凝胶。
