In this work, we reported an anthracene carboxyimide-based chemosensor (AC-Phos) for colorimetric and ratiometric fluorescence detection of highly toxic phosgene, which displayed rapid response (<5 min) toward phosgene with a high selectivity and a low detection limit (2.3 nM). Furthermore, a facile testing membrane with a polystyrene immobilizing chemosensor has been fabricated for real-time visualizing of gaseous phosgene.
