Several fluorescent probes based on hemicyanine for the detection of SO2 derivatives

Author affiliations

Abstract

It's of great importance to detect SO2 and its derivatives (bisulfite/sulfite) because of their harmful effects on the environment and human health. In this work, three probes based on hemicyanine were designed and synthesized to detect SO2 derivatives in aqueous solution (containing 10% DMSO) through a 1,4-addition reaction. All probes displayed rapid and selective responses toward SO2 derivatives, and could quantitatively detect HSO3 with detection limits of 8.7 μM, 6.5 μM and 4.0 μM, respectively. Meanwhile, the color of the probe solution changed immediately (within 10 s), which provides a simple way to recognize bisulfite with the naked eye. Finally, visual detection of SO2 gas has been successfully realized.
