摘　　要：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 increasing development of supramolecular chemistry,stimulus-responsive supramolecular gels as a supramolecular material attract more attention.Supramolecular gels are self-assembled by non-covalent forces,when supramolecular gels are stimulated by temperature,light,pH,chemistry substances,mechanical strength etc.,the gels can produce the appropriate response,such as sol-gel transition,change in color o fluorescence.Stimulus-responsive supramolecular gels have very good prospects in the areas of ion recognition materials,self-healing materials and biomaterials.This paper reviews the progress of stimulus responsive supramolecular gels in the past five years.According to the different types of stimulation,the gels are devided into the following categories：heat-sensitive organic gel,chemistry substances and pH-responsive supramolecular gels,light-sensitive organic gel,redox-responsive supramolecular gel,mechanical force-responsive supramolecular gels and multiple stimuli-responsive supramolecular gel.According to these classifications,the supramolecular gels are introduced and at the same time,the developing orientation for further research is presented.
