中文摘要: 近年来低分子量凝胶因子在溶剂中自组装机制研究,成为超分子化学领域的研究热点,但目前没有对凝胶因子结构参数定量化进行研究的报道。 本课题设计一系列具有不同基团的多元醇缩醛衍生物凝胶因子,表征其在有机溶剂、离子液体和碱溶液电解质三种体系中的凝胶性能,采用基团贡献法构建凝胶因子可凝胶预测模型,在不同溶剂体系中研究凝胶因子结构与凝胶性能的关系,研究凝胶因子结构参数与溶剂性能参数之间关系。在凝胶预测理论模型的基础上,设计并合成新凝胶因子,研究其在离子液体和碱溶液电解质中应用。 将基团贡献法应用于凝胶体系研究,建立可凝胶性理论模型,可以为新型凝胶因子设计提供理论依据,具有重要的研究价值。

英文摘要: In recent years the research of low molecular weight gelator self-assembly mechanism in solvent has attracted a great deal of attention in supramolecular chemistry field. At present there is a lack of correlative reports about structure of gelator parameters quantitative study. In this projects a series of poly alcohol acetal derivatives as gelators are designed and synthesized. The products gelation properties are tested in organic solvent, ionic liquid and aqueous alkali gel electrolytes system. Gelation formation prediction model of gelator will be proposed by group contribution method. The relation model between structure of gelator and gelation properties will be studied in different solvent system. The relation between gelator structure parameters and solvent solubility parameters will be studied. New gelators will be designed and screened based on the gelation predicting model. New applications of these gelators are developed in ionic liquid and aqueous alkali gel electrolytes. Applying group contribution method in researching gel system, the construction of gelation formation prediction model has important scientific research value and can provide theoretical support for designing new gelators.
