随着超分子化学的日益发展,刺激响应型超分子凝胶作为一种超分子材料受到人们广泛关注。超分子凝胶是由非共价键作用力自组装而成,基于这一特性,当超分子凝胶受到外界刺激(如温度、光、pH、化学物质、机械力等)时,该凝胶能够产生响应,如溶胶-凝胶转化、颜色变化或荧光变化等。刺激响应型超分子凝胶在离子识别材料、自修复材料、生物材料等领域展现出了非常好的应用前景。本文综述了近五年来刺激响应型超分子凝胶的研究进展,并根据刺激种类的不同,将超分子凝胶分为以下几类:热敏感型超分子凝胶、化学物质和pH响应型超分子凝胶、光敏感型超分子凝胶、氧化还原响应型超分子凝胶、机械力刺激响应型超分子凝胶和多重刺激响应型超分子凝胶。本文根据上述分类对超分子凝胶进行了介绍,同时对该研究领域作了展望。
With the development of supramolecular chemistry, stimulating responsive supramolecular gels have drawn much attention as a supramolecular material. Based on this property, supramolecular gels are self-assembled by non-covalent forces. When the supramolecular gels are subjected to external stimuli (such as temperature, light, pH, chemicals, mechanical forces, etc.) Can produce responses such as sol-gel conversion, color change or fluorescence changes. Stimuli-responsive supramolecular gels have shown promising applications in ion-recognition materials, self-healing materials, biomaterials and the like. This review summarizes the research progress of stimulating responsive supramolecular gels in the recent five years. According to different types of stimuli, supramolecular gels are divided into the following categories: heat-sensitive supramolecular gels, chemical substances and pH-responsive super Molecular gels, light-sensitive supramolecular gels, redox-responsive supramolecular gels, mechano-stimuli responsive supramolecular gels, and multi-stimuli responsive supramolecular gels. This article based on the classification of supramolecular gels were introduced, at the same time, made a preview of the field of research.
