Abstract:
1, 3:2, 4-di-p-methylbenzylidene-D-sorbitol (MDBS) is known to be an efficient sorbitol derivative gelator. A series of allyl sorbitol gelators have been designed in contrast to MDBS. Self-assembly and gel mechanism of gelators in solvents were studied by force between gelators, molecular and hydrophilic interaction. 4 gelators' behavior to 30 solvents and minimal gelation concentration was investigated. It was found that the gelation behavior was related to the molecular structure of gelators. The introduce of allyl significantly improved the ability of gelators. (UV Vis) spectroscopy results revealed the main driving forces for the formation of gels. The fibrous and three-dimensional network of the gels was observed by scanning electron microscopy (SEM).
