摘要：As one of the main atmospheric pollutants, sulfur dioxide (SO2) can be easily inhaled and turned into sulfite and bisulfite, which is harmful to both human health and ecological environment. Therefore, it is of significance to develop an effective method to detect the trace SO2 derivatives-SO32- and HSO3-. Herein, we synthesized a semi-cyanine-coumarin hybrid dye for detection of SO32- and HSO3-. Based on the nucleophilic addition of HSO3-/SO32- to the vinyl group, Probe 1 showed high response speed, selectivity, and sensitivity towards SO32- and HSO3-. Upon addition of HSO3-/S-3(2-), color obviously changes from blue to yellow which can be differentiated by naked eyes. Probe 1 displays colorimetric and ratiometric response toward HSO3- and SO32-. The detection limit is as low as 27.6 nM and the signal-to background ratio in fluorescence intensity can reach 35-folds. Moreover, Probe 1 showed high selectivity and anti-interference ability in the co-existence of the environmental and biologic species. (C) 2016 Elsevier Ltd. All rights reserved.
