Hydrogen peroxide (H2O2) plays an important role in various physiological and pathological processes in the form of molecular signals. Thus, it is of great significance to detect hydrogen peroxide in living cells or organisms quickly, efficiently and sensitively. In this study, a novel ratiometric fluorescent probe was designed to show the ratiometric fluorescence response to hydrogen peroxide. The probe showed the advantages of good selectivity, high sensitivity, low cytotoxicity and fast reaction rate in hydrogen peroxide detection. The probe also provided excellent performance in detecting both exogenous and endogenous hydrogen peroxide in living cells.
