An AIE probe for the fluorescence and colorimetric sensing of La.

In this work, a fluorescent probe with aggregation-induced emission effect was synthesized by grafting naphtho[2,3-]furan-1,3-dione and 2-hydrazinylbenzo[]thiazole. The probe could recognize La selectively and sensitively accompanied with an obvious fluorescence and color change from green to blue. Moreover, with the help of AIE properties, probe N achieved the detection of La in the solid state.
