Due to the remarkable sensitivity to external stimuli incorporated with biocompatible property, supramoleeular hydrogel based on low-molecular-weight gelator has gained immense interests. This material has many potential application areas, such as smart gel, tissue engineering, etc. The design and preparation of low molecular weight organic gelators as well as understanding of the mechanism of the gelation proeess have attracted great attention recently and beeome the key point for supramoleeular hydrogel. In this paper, basic concepts of supramoleeular hydrogel are introduced firstly. The structural motifs and functions of the supramoleeular hydrogels are reviewed in detail. Finally, the current research and perspective of supramolecular hydrogel are discussed.
