The curmarine-based gelator 1 was synthesized by several steps, and the gelation ability was evaluated in pure and a mixture of organic solvents. The gelator 1 could be gelate a pure ethanol, toluene, dichrolomethane. In addition 1 formed a gel in different composite of ethanol/DMSO (10:1 ~ 5:5 v/v%). SEM images of organogels prepared at different composite solvents exhibited a typical fiber structure with 70-100 nm diameters. The luminescence properties of organogels prepared at different composite of ethanol/DMSO by fluorometry and time resolved fluorescence lifetimes. Interestingly, the organogel showed dramatic luminescence enhancement, which was dependent on the ethanol/DMSO ratio of the solvent. The luminescence lifetimes of the organogel were particularly long, on the order of several nanoseconds. The luminescence lifetimes were also slightly dependent on the solvent composition.
