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 process have attracted great attention recently and become the key point for supramolecular hydrogel . In this paper , basic concepts of supramolecular hydrogel are introduced firstly . The structural motifs and functions of the sup
