Chemical Sensing Technology towards Global Public Safety (I): Fluorescent Probes for Detection of Phosgene

Phosgene, an important chemical warfare agent (CWA), has received great attention in the field of counterterrorism and public safety monitoring.Developing new sensing methods/tools for efficient detection of phosgene is an urgent challenge to be solved.For chemists, it is pivotal to create fast, low cost, portable, selective, sensitive, as well as visualizable chemical sensors/probes for real-time phosgene detection.This article reviewed and discussed current trend and statement of phosgene-specific fluorescent probes, providing concise "fast glance" and systematic "big picture" to the related researchers and public safety engineers.Moreover, the outlook in this field was also stated.
