摘要
A turn-on fluorescent probe ACR {6 '-[2-(azidomethyl)benzoy1]-7 '-chloro-N,N-diethylrhodol} for selective detection of H2O2 was developed. An ester bond was broken by the nucleophilic substitution of H2O2 which released strong fluorescence. Probe ACR was proved to be made up" of three essential parts, chlorine atom, azide group and an active carbonyl. This probe showed high selectivity for H2O2 and a linear fluorescence intensity enhancement with a wide range of concentrations of H2O2. Fluorescence imaging experiments in HeLa cells indicated its potential to image H2O2 in biological systems. (C) 2017 Elsevier B.V. All rights reserved.
