新型无氢键全氟烷基胶凝剂-双（2，2，3，3，4，4，5，5，6，6，7，7，8，8，8-十五烷基辛基）异邻苯二甲酸酯（1 m），双对苯二甲酸（2，2，3，3，4，4，5，5，6，6，7，7，8，8，8-十五氟辛基）酯（1 p）和三-合成了1，3，5-三羧酸（2，2，3，3，4，4，5，5，6，6，7，7，8，8，8-十五氯辛基）苯酯（2）。采用密度泛函理论B3 LYP/cc-pVDZ方法研究了它们的分子结构.考察了1 m、1 p和2的凝胶化能力，并与它们的正辛基同系物1 m '、1 p'和2 '进行了比较。这些凝胶因子在普通有机溶剂中均不能形成凝胶，但在含氟溶剂中形成凝胶效果较好。
Novel perfluoroalkyl gelators without hydrogen bonds-bis(2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-pentadecafluorooctyl) iso-phthalate (1m), bis(2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-pentadecafluorooctyl) terephthalate (1p), and tris-(2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-pentadecafluorooctyl) benzene-1,3,5-tricarboxylate (2)-were synthesized. Their molecular structures were investigated by density functional theory calculations at the B3LYP/cc-pVDZ level. The gelation abilities of 1m, 1p, and 2 were examined and compared to their normal octyl homologues 1m', 1p', and 2'. None of the gelators could be gelated in common organic solvents, but gelated well in fluorinated solvents.
