设计合成了一种中心为三乙基氨基,酰胺基作为氢键连接基团,柔性的烷基链连接偶氮苯基团的含多种分子间弱相互作用的三枝状有机凝胶因子1.由于偶氮苯基团处于分子的外缘,在THF溶液中,凝胶因子1表现出良好的光致变色行为.凝胶性能测试中,分子间存在氢键作用、π-π相互作用等使得该化合物在醇类、有机酸类和乙腈等极性溶剂中极易形成稳定的有机凝胶.在少数的非极性溶剂,如正己烷和环己烷中也可以形成稳定凝胶,并且随着溶剂极性的不同,凝胶形貌呈现出规则的纤维状或带状结构.

A novel tripodal organogelator 1,functionalized by three amide and three azobenzene moieties linked with three alkyl chains was designed and synthesized.In THF solution of 1,it well undergoes photochromic property because the azobenzene moieties are in the outer region of the molecule.In the gelating experiment,the cooperation of hydrogen bonds and π-π interactions make the gelator 1 have the ability for gelating a wide variety of organic solvents,especially the polar solvents,such as alcohol,carboxylic acid and acetonitrile;also for some apolar solvents,such as cyclohexane and hexane.The morphologies of the xerogels prepared from this gelator depend on the polarity of the gelling solvent and exhibit fibres or belts structures regularly.
