摘　　要：旨在报道一种新型的水凝胶因子,可在室温下形成凝胶。通过向安替比林-环己烷羰基酯(物质1)的乙醇溶液中加入定量的水可原位、即刻形成凝胶,利用有机合成方法得到了含有吡唑啉酮和环己胺基团的凝胶因子,通过IR,XRD,SEM,TEM等手段对凝胶进行了表征。研究发现,在水含量较低时,凝胶因子分子聚集成为囊泡形状;随着含水量的增大,它的聚集体能实现由0D囊泡向不规整的2D片状结构的转变,并胶凝溶剂。A new kind of hydro-gelator antipyrine-cyclohexane carbonyl ester （substance 1） was introduced, which could gel in water at room temperature. The addition of a certain amount of water into the solution of 1 in alcohols could induce instant and in situ gelation. The organogelator combining antipyrine and methylcyclohexyl groups were obtained via organic synthesis method. The gelation properties were characterized by IR, XRD, SEM and TEM. The study shows that the compound 1 assembles into 0D vesicle with the lower content of water, while with the higher concentration, it aggregates into irregular 2D sheet structure, and gels the mixed solvents.
