In this work, a novel 7-hydroxybenzoxazinone-based fluorescent probe (<b>PBD</b>) for the selective sensing of biothiols is reported. Upon treatment with biothiols, <b>PBD</b> shows a strong fluorescence enhancement (up to 70-fold) and a large Stokes shift (155 nm). Meanwhile, this probe exhibits high resistance to interference from other amino acids and competing species. <b>PBD</b> features good linearity ranges with a low detection limit of 14.5 nM for glutathione (GSH), 17.5 nM for cysteine ...[more]
