摘      要：Two new fluorescent organogelators based on cholesterol containing benzothiadiazole group have been de- signed and synthesized. Three methods for gels preparation have been presented, such as heating-cooling process, ultrasonic treatment and mixed solvents under room temperature. For both of the gels, their states and emission col- ors exhibit striking changes upon addition of Hg^2＋. The gelation properties, structural characteristics and fluores- cence of the gels were studied by FT-IR, UV-Vis absorption and PL spectra. The underlying mechanism of gelation property was studied by X-ray diffraction combined with theoretical calculation, and the important role of π-π in- teractions in forming the gels has been proved.
