An AIE probe for the fluorescence and colorimetric sensing of La3+

Abstract

In this work, a fluorescent probe N with aggregation-induced emission effect was synthesized by grafting naphtho[2,3-c]furan-1,3-dione and 2-hydrazinylbenzo[d]thiazole. The probe N could recognize La³⁺ 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 La³⁺ in the solid state.
