A turn‐on fluorescent probe Coumarin‐SO2 based on a nucleophilic addition reaction was developed for the rapid detection of SO 3 2– in aqueous media. The probe Coumarin‐SO2 displays excellent water solubility, fast response, highly sensitivity and highly selectivity over other biological related species. More importantly, living cell imaging experiments indicate the feasibility of using the probe for the detection of SO 3 2– in biological systems. Copyright © 2015 John Wiley & Sons, Ltd.
