二组分凝胶的研究进展及功能

The Research Progress and Functions of Two-component Supramolecular Gels

超分子凝胶由小分子量胶凝剂在溶剂介质中通过多种非共价键的作用力自组装形成纳米纤维的交缠三维网络结构,从而将大量的溶剂分子束缚在其网络空间中,形成宏观可视的半固态软物质材料。其中二组分凝胶因其多功能化,具有更多的调控位点等成为了超分子凝胶领域的研究热点之一,本文主要介绍了功能分子掺杂的二组分凝胶,及其在分子识别、光电性能及手性传递方面的应用。

Supramolecular gels are semi-solid systems,in which liquid phase is immobilized by the formation a three-dimensional network composed of self-assembled gelator fibers and their entanglements.In comparison with gels constructed fromindividual molecules,two-component supramolecular gels have witnessed our eyes,owing to their tunability and responsiveness to different stimuli. This article mainly describes one type of two-component self-assembling gelation systems,in which one of the components forms a gel in its own right and the addition of the second component modifies the gelation process as a consequence of complex formation. The applications in molecular recognition,photoelectric properties,transfer of charity were also discussed.
