Abstract | Hydrogen peroxide (H2O2) has been recognized as one of the most significant ROS (reactive oxygen species) in human health and disease. Because of the intrinsic attributes of H2O2—such as its low reactivity under physiological pH—it is exceedingly challenging to develop small‐molecule fluorescent probes with high selectivity and sensitivity for visualization of H2O2 in an intricate biological milieu. To address this gap, a rationally designed tandem Payne/Dakin reaction is reported that is specific to molecular recognition of H2O2. New H2O2 probes based on this unique chemical strategy can be easily synthesized by a general coupling reaction, and the practical applicability of those probes has been confirmed by the visualization of endogenously produced H2O2 in living cells. In particular, starvation‐induced H2O2 production in mouse macrophages has been detected by the novel probe in both confocal imaging and flow cytometry. This tandem Payne/Dakin reaction provides a basis for developing more sophisticated molecular tools to interrogate H2O2 functions in biological phenomena. |
