Two novel aggregation-induced emissioncompounds harnessing Excited-StateIntramolecularProtonTransfer process based on salicylideneaniline derived from tetraphenylethylene and cholesterol moieties were synthesized and characterized. One of the compounds could gelate in cyclohexane exhibitinggelation-inducedenhancedemission and the emission intensities can be reversibly changed with the gel-solution
The emission compounds possess different gelation behavior in organic solvents. The emission intensities of the emission compounds can be reversibly changed with the gel–solution transition by alternate cooling and heating. Moreover, the color and emission of these organogelators can be repeatedly switched by various external stimuli including pressing, heating and solvent-fuming. These new compounds
