摘要 1, 3∶2, 4-二(对甲基苄叉)-D-山梨醇(MDBS)是一种凝胶能力突出的山梨醇缩醛类凝胶因子,对比MDBS本设计合成一系列烯丙基山梨醇缩醛,并通过凝胶因子之间的作用力、分子的几何构型及亲疏水作用等方面研究了凝胶因子在溶剂中的自组装及凝胶机理。考察了4种凝胶因子对30种常见有机溶剂的凝胶能力,以及凝胶因子在不同溶剂中的最低凝胶浓度。结果表明,凝胶因子的凝胶能力依赖于凝胶因子的分子结构,烯丙基的引入显著提高了凝胶因子的凝胶能力。研究了凝胶的形成机理,通过紫外光谱研究自组装力,通过场发射扫描电镜可以观察到凝胶呈纤维状和三维网状结构。

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).
