A new strategy for HOCl-specific fluorescent probes has been reported based on a selenoxideelimination reaction. Probes CM1 and CM2 were synthesized as the first fluorescent probes containing an arylseleno moiety for hypochlorite according to this strategy. Both probes displayed excellent properties, including high selectivity and sensitivity, fast response, and pH independency toward hypochlorite

The aromatisation of 7-diethylamino-3,4-dihydrocoumarin provides an alternative fluorescent probing technique to selectively detect the concentration of superoxide anion in solution. In addition, we reported the advantage of evaluating O2˙− sensing probes in anhydrous DMSO instead of in aqueous buffers when using KO2 as the surrogate of O2˙−.
