Perfluorinated gelators for solidifying fluorous solvents: effects of chain length and molecular chirality

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. The gelation ability for C6F6 was investigated. The length of a perfluoroalkyl chain (n = 4–9) was found to affect critically the gelation properties such as gel stability, chirality effects and aggregation modes in fibrils.
