A novel NIR fluorescent probe for the double-site and ratiometric detection of SO2 derivatives and its applications

Author affiliations

Abstract

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.
