| Hypochlorous acid is a highly reactive oxygen species. It is of great significance to develop new luminescent probes for detecting hypochlorous acid in the field of bioscience and environmental chemistry. In this work, a highly sensitive and selective Ru(II) complex-based phosphorescent probe,[Ru(bpy)2(NHM-bpy)](PF6)2, has been designed and prepared for the deternination of hypochlorite in aqueous solutions. The weakly luminescent probe can selectively react with hypochlorite to yield its carboxyl compound, accompanied by a remarkable enhancement in phosphorescence intensity. Upon reactions with various reactive oxygen species, the probe displayed high specificity for hypochlorite.The probe was used for the phosphorescence detection of hypochlorite, which showed a good linearity with a detection limit of0.61μmol/L. The probe has been used in the detection of hypochlorite in practical water samples. The results indicate the assay has good precision and accuracy. |
