With a purpose of solidifying fluorous solvents, a novel series of perfluorinated gelators based on 1,2-diaminocyclohexane (denoted as CFn: n = the number of carbon chain in perfluoroalkanoyl moiety) were developed.
为了加固氟溶剂,基于1,2-二氨基环己烷(表示为CFn: n = 氟代烷酰基中碳链的数量)的全氟基凝胶剂新系列被开发出来。

A chiral low-molecular weight gelator, N,N′-diperfluoroheptanoyl-1,2(R,R)- or -1,2(S,S)-diaminocyclohexane, was prepared to form a gel of acetonitrile. The conformation of the gelator in fibrils was determined by vibrational circular dichroism spectra, providing a molecular model for self-assembly in a helical fibril.
