- W4224120151 abstract "• A “turn on” cycometalated iridium(III) complex-based sensor for detection of HOCl based on −C = N−NH− bond was designed and synthesized. • The sensing platform shows high sensitivity and anti-interference for detection of HOCl in PBS/DMF solution and real water samples. • The detection mechanisms involved transformation of benzenesulfonylhydrazine to formyl group due to strong oxidant ability of HOCl. Hypochlorous acid (HOCl), a kind of reactive oxygen species (ROS), has been reported to be related to many human diseases, such as Parkinson's diseases, arthritis and cancers. Herein, a red-emission Ir(III) complex-based probe 1 for quantitative detection of HOCl was prepared and characterized by 1 H and 13 C NMR, IR and HRMS. For probe 1 , benzenesulfonylhydrazine group was introduced to the main N^C ligands phenylpyridine to quench fluorescence due to the isomerization of C = N bond. After reaction with HOCl in 30% DMF/PBS solution, the benzenesulfonylhydrazine group was taken off and fluorescent complex Ir-CHO was generated. The fluorescence intensity at 625 nm was significantly enhanced, and finally increased by 23 times. The experiment results demonstrated that probe 1 possessed large Stokes shift (ca. 195 nm), low detection limit (1.3728 × 10 −6 M), fast response (25 s), and high selectivity toward HOCl without interference from other ions and bio-related species. In addition, probe 1 exhibited good stability and water solubility. Moreover, it could be further applied in actual water for quantitative detection of HOCl with high recovery rate (95% − 101%)." @default.
