摘要:
Hydrogen sulfide (H 2 S) is a common toxic gas that threatens the quality and safety of environmental water and food. Herein, a new near -infrared fluorescent probe DTCM was synthesized and characterized by single crystal Xray diffraction for sensing H 2 S. It exhibited a remarkable "turn -on " near -infrared (NIR) emission response at 665 nm with a remarkably massive Stokes shift of 175 nm, super -rapid detection ability (within 30 s), excellent photostability, high selectivity and sensitivity (limit of detection, LOD = 58 nM). Additionally, the probe was successfully utilized for the detection of H 2 S in environmental water samples. The DTCM -loaded test papers enabled convenient and real-time monitoring of H 2 S produced by food spoilage.
