以不同长度烷烃取代靛红和联苯胺为底物合成了新型凝胶因子，通过FT-IR、NMR等表征方法对凝胶因子的结构进行了分析，研究了产物DICB-n（n=10、12、16）在不同有机溶剂中的凝胶性能。结果表明，DICB-10、DICB-12可在二甲基亚砜（DMSO）中形成稳定凝胶，产物凝胶性能优良；产物DICB-10对钴离子可产生特异性响应。通过刺激响应性质测试实验可知，凝胶作为一种软物质对机械力和热可产生结构上的变化，在智能材料领域具有潜在的应用前景。

A new kind of gelator is synthesized based on benzidine and isatin with different length of alkyl chain,the structure of the gelator is characterized by FT-IR and H NMR spectra.The gel ability of the gelator is explored in different solvents.Results show that DICB-10,DICB-12 gelators can form stable gels in DMSO,and the performance of gels products are good.DICB-10 can generate specific response to cobalt ions.As a soft material,gel can change its structure in response to mechanical force and heat,which makes gel have potential application.
