A fluorescent probe composed of BODIPY and 2,4-dinitrophenylhydrazine was designed for the detection of CIO-. The oxidizing reaction between probe and CIO- resulted in a distinct fluorescence enhancement together with a color variation from pink to orange. This probe showed excellent selectivity to CIO- among various ions including common reactive oxygen species and high sensitivity with a detection limit of 228 nM. A fast response (7 min) was observed, which made the probe a promising method in real-time detection. Furthermore, this probe was successfully applied to monitor CIO- in real-life water and living cells. (C) 2017 Elsevier B.V. All rights reserved.
