A simple Schiff base probe,namely 2-(((E)-(3H-benzo[f]chromen-2-yl)methylene)amino)-3-aminomaleon-itrile(1),was prepared by the condensation reaction,which was characterized through 1H NMR,13C NMR,ESI-MS,and single crystal X-ray diffraction.The fluorescence experiments indicated that probe 1 was non-emissive,while hypochlorite(ClO-)could induce a strong emission of the probe at 530 nm.The response of probe 1 toward ClO-was highly sensitive and finished within a few seconds.The ClO--promoted decomposition of probe 1 was suggested by spectral and theoretical methods.Furthermore,the probe was applied to imaging exogenous and endogenous ClO-in living cells,zebrafish,and Arabidopsis thaliana.CCDC:2353078.
