Abstract:Vanillin and ortho‐vanillin are the most important flavoring additives used in the food industry at a large scale. Herein, the aggregation‐induced emission (AIE) behavior of commercially available 3‐hydroxy‐2‐naphthohydrazide (3HN) was explored and applied for the detection of vanillin and ortho‐vanillin. The weakly fluorescent 3HN in DMSO showed fluorescence enhancement at 500 nm with the increase in HEPES or PBS buffer (pH 7.4) fractions in DMSO. The 3HN in DMSO containing 30% HEPES buffer is used as Probe 1… Show more
Herein, an aggregation-induced emission (AIE) luminogen (AIEgen) NANH was developed by condensing equimolar amount of 2-hydroxy-1-naphthaldehyde and 3-hydroxy-2-naphthohydrazide. The AIE behaviour of NANH was explored in a mixed DMSO-H2O (HEPES...
