Abstract

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.
