摘要：

The benzoxazole derivative gelator 1 forms a stable DMF/toluene cosolvent gel with dramatically enhanced fluorescence emission compared to its mother solution. The translucent colorless gel was changed to a solution with strong greenish fluorescence in the presence of fluoride anion with disruption of the gel structure.
