A paper-based chemosensor for highly specific, ultrasensitive, and instantaneous visual detection of toxic phosgene

A chemosensor containing an o -hydroxyaniline unit as the reaction site was developed for colorimetric and fluorimetric detection of phosgene, which showed fast response (15 s), high specificity, and an extremely low detection limit. The chemosensor was incorporated into paper strips for visual dete...

Summary:A chemosensor containing an o -hydroxyaniline unit as the reaction site was developed for colorimetric and fluorimetric detection of phosgene, which showed fast response (15 s), high specificity, and an extremely low detection limit. The chemosensor was incorporated into paper strips for visual detection of phosgene vapor. A chemosensor containing an o -hydroxyaniline unit as the reaction site was developed for colorimetric and fluorimetric detection of phosgene, which showed fast response (15 s), high specificity, and an extremely low detection limit.
