摘      要：1,3:2,4-di-p-methylbenzylidene-D-sorbitol(MDBS)is known to be an efficient sorbitol derivative *** new sorbitol derivative gelators were designed and synthesized in contrast to MDBS in order to study the gel properties of gelators with different *** gelation behavior to 30 solvents was *** was found that the gelation behavior was related to the molecular structure of *** with MDBS,the gelator with more hydroxyl in the molecular structure could gel water and that with more aromatic ring could gel aromatic *** fibrous and three-dimensional network of the gels was obtained by scanning electron microscopy(SEM).Ultraviolet-visible(UV-Vis)spectroscopy revealed thatπ-πinteraction was one of the main driving forces for the formation of ***π-πstacking of gelation increases with the number of aromatic rings in the molecular structure of *** transform infrared(FT-IR)spectroscopy revealed that the hydrogen bonding was also the main driving force for the formation of *** layered structure of the gels was studied by X-ray diffraction(XRD).
