摘要： A new fluorescence probe 1 for sulfur dioxide derivatives has been developed which acts through nucleophilic addition of the derivatives and shows high stability, specificity, and sensitivity. In the presence of SO2 derivatives, the fluorescence intensity of probe 1 significantly decreases within a short time period of 40 s, along with a low detection limit of 0.32 mu M. Fluorescence imaging capability of probe 1 was also investigated, showing clear detection of SO2 derivatives in living cells. The results indicate that this probe has a great potential for the detection of SO2 derivatives in broad biological and relevant samples.
