摘要
A new 7-hydroxy-3-methyl-benzoxazinone based fluorescent probe for thiophenols has been designed and synthesized. The probe displays highly selective and sensitive detection to thiophenols over other common analytes with instant response and remarkable large Stokes shift. It's noteworthy that biothiols, aliphatic thiols, and reducing anions do not perturb the sensing of thiophenols. The limit of detection of the probe was calculated as low as 24 nM for thiophenols. Finally, the utility of probe was illustrated by the detection of thiophenol in real environmental water samples.
