摘要：

Direct detection of picric acid in water samples is very important for social security and environmental protection. Herein, a novel donor-acceptor type fluorophore 3-(benzyloxy)-2-(4-(di-p-tolylamino) phenyl)-4H-chromen-4-one has been designed, and synthesized. Due to its aggregation-induced emission enhancement characteristic, this fluorophore showed a very strong fluorescence in water. This fluorophore was then employed as highly sensitive chemosensor for picric acid, with a limit of detection of 370 nM in water. Moreover, this sensor showed very high selectivity towards picric acid among interfering nitroaromatics. At last, the sensing mechanism was carefully studied by using DFT computation and NMR spectra. This work provided a practical and reliable detection method for picric acid in water samples. (C) 2017 Elsevier Ltd. All rights reserved.
