摘要： A feasible double-site near-infrared (NIR) fluorescent probe Q5 based on xanthenes was developed. Probe Q5 showed clearly HSO3- induced changes in the fluorescence ratio of two well-separated NIR and VIS peaks, showing excellent selectivity compared with other analytes. And the detection limit of the probe for HSO3- was found to be 89 nM. Furthermore, fluorescence imaging experiments of HSO3- in CEM cells revealed that the probe has potential application value in biological systems.
