Toward public security monitoring: A perspective of optical molecular probes for phosgene and mustard gas detection

Phosgene and mustard gas are highly toxic chemicals that severely threaten public security and human health. To ensure public security, monitoring these chemical warfare agents (CWAs) is necessary. Many fluorescent probes have been developed for detecting CWAs because of their high sensitivity, facile manipulation, and visual signal output. In this review, we introduced the recent progress of various fluorescent probes for phosgene and mustard gas detection, including recognition sites, sensing mechanisms, and structure-function relationships. Further-more, the challenges and perspectives of fluorescent probes for CWAs were briefly stated. We hope this review will provide constructive information to develop the most advanced fluorescent probes towards CWAs.
