Triamide gelators

Novel triamide gelator 44 based on 4,4, 4"-triaminotriphenylamine and stearic acid was prepared by the group of Shirota [34]. Triaminotripheny-lamine was reacted with high-purity stearic acid in mesitylene at 164 °C for 8 h with constant removal of water (Scheme 10).

Much more efficient triamide geiators were prepared from cis-1,3,5-cyclohexanetricarboxyhc acid and long-chain alkylamines (Fig. 8) [33]. Geiators 42 and 43 exhibited excellent gelation of various hpophihc solvents (hexane, cyclohexane, benzene, toluene, chlorobenzene, and pyridine) and also of kerosene.
