报道了一种新的比率荧光探针，用于检测剧毒硫酚类化合物。为了产生比率荧光信号变化的硫酚，这种探针被设计成使用香豆素-萘酰亚胺二联体作为荧光共振能量转移（FRET）平台和二硝基苯基醚作为识别单元。该探针具有高选择性和灵敏度，在温和的条件下快速检测过程和显着的荧光发射比变化（高达340倍）。将该探针应用于真实的水样中苯硫酚的检测，获得了成功的应用。
A new ratiometric fluorescent probe for the detection of highly toxic thiophenols was reported. To produce ratiometric fluorescence signal changes for thiophenols, this probe was designed to use a coumarin–naphthalimide dyad as the fluorescence resonance energy transfer (FRET) platform and dinitrophenyl ether as the recognition unit. This probe features high selectivity and sensitivity for thiophenols with a rapid detection process under mild conditions and remarkable fluorescence emission ratio changes (up to 340-fold). The application of this probe for thiophenol detection in real water samples was successfully applied.
