瓜环基超分子水凝胶的构筑及应用

Construction and Application of Cucurbit [n]uril-based Supramolecular Hydrogel

瓜环基超分子水凝胶通过分子间弱相互作用驱动而成,具有良好的刺激响应性能。根据驱动力类型瓜环基超分子水凝胶可分为三种类型:依托瓜环自身诱导的外壁作用为主、氢键作用为辅助驱动力;依托瓜环主客体包结作用为主要驱动力;依托瓜环主客体端口作用为主要驱动力。对国内外以及本实验室报道的瓜环基超分子水凝胶的结构及应用进行归纳总结,为进一步开发性能优异的水凝胶提供理论依据。

The cucurbit[n]uril-based supramolecular hydrogels are formed by weak interaction and has good irritation and response properties.According to the type of driving force,the cucurbit[n]uril-based supramolecular hydrogel can be divided into:the driving force mainly relies on the outer surface interaction of cucurbit[n]urils,supplemented by the hydrogen bond;the driving force mainly depends on the host-guest inclusion interaction of cucurbit[n]urils;the driving force mainly depends on the host-guest exclusion interaction of cucurbit[n]urils.This paper summarizes the structure and application of cucurbit[n]uril-based supramolecular hydrogels reported by others and our laboratory,and provides a theoretical basis for the further development of hydrogels with excellent performance.
