摘要：
Chemical warfare agents (CWAs) have been notorious for a century, especially sarin and mustard gas, which have produced intolerable menace to civilian lives and environmental security. As a result, developing simple, rapid, portable, sensitive, and selective detection technologies for CWAs is critical. This review primarily covered the recent progress in developing organic fluorescent probes for detecting phosgene, mustard gas, and nerve agents and their mimics. The review mainly discussed various sensing reactions utilized in the covalent strategies like cyclization, elimination, phosphorylation, alkylation, and sprioring-opening reaction, as well as the supramolecular approaches. The comparison of these probes highlighted the successful development of fluorescent probes for CWAs, some with detection limits in nano mol/L in solution and ppb scale in vapor state within seconds. These will contribute to a more effective system for detecting and monitoring CWAs in the future and improve the ability to respond to chemical attacks. Finally, the review discussed the limitations of current probes, emphasizing the need for on-site and real-time detection. It also called for research into new mechanisms and kits for rapid early warning of various CWAs to facilitate emergency handling and decontamination.
