A new carbazole-based colorimetric and fluorescent probe CBB for the detection of bisulfite (HSO3) has been developed via nucleophilic addition reaction. Probe CBB can detect HSO3 with excellent sensing properties including high selectivity and sensitivity, fast response (5 s). More importantly, probe CBB system not only can be applied to monitor HSO3 in environment with excellent solid properties based on test strips but also can be used for the detection of HSO3 in real-water samples with satisfactory results.
