一种手性胶凝剂，RR-或SS-N，N '-二全氟辛酰基-1，2-二氨基环己烷，胶凝外消旋2-丁醇。外消旋体的凝胶稳定性最好，随着凝胶因子光学纯度的增加，其稳定性降低。值得注意的是，在对映异构体过量的狭窄区域（ee = 0.2-0.4）中形成特征性螺旋盘绕原纤维。对映体的促进作用的建议。
A chiral gelator, RR- or SS-N,N'-diperfluorooctanoyl-1,2-diaminocyclohexane, gelated racemic 2-butanol. The gel was most stable at the racemic mixture, its stability lowered with the increase in the optical purity of the gelator. Notably, characteristic helically coiled fibrils were formed in the narrow region of enantiomer excess (ee = 0.2-0.4). Promotion effects of the antipodal enantiomers are proposed.
