The screening of highly toxic chem. vapor is critical for environmental monitoring and human health maintenance. Herein, we reported a chemosensor (AC-HPD) for rapid and specific detection of highly toxic oxalyl chloride vapor, which adopted anthracene carboxyimide as a fluorophore and 3-aminopropanol as the reaction site. Upon coupling of oxalyl chloride with NH and OH groups, AC-HPD exhibited remarkable colorimetric and ratiometric fluorescence dual-mode responses towards oxalyl chloride via the intramol. charge transfer effect. AC-HPD could determine oxalyl chloride with features of rapid response, excellent specificity, low detection limit (95 nM), as well as obvious color and fluorescence change. Furthermore, AC-HPD-embedded test strip was successfully fabricated and used as a flexible sensing device for rapid, sensitive and visible monitoring oxalyl chloride vapor. After reading the article, we found that the author used 3-Aminopropan-1-ol(cas: 156-87-6Category: alcohols-buliding-blocks)
3-Aminopropan-1-ol(cas: 156-87-6) belongs to anime. Amines have a free lone pair with which they can coordinate to metal centers. Amine–metal bonds are weaker because amines are incapable of backbonding, but they are still important for sensing applications.While stronger than hydrogen bonds, amine–metal bonds are still weaker than both covalent and ionic bonds.Category: alcohols-buliding-blocks
