TL;DR: A highly selective fluorescent sensor o-Pab for phosgene with a BODIPY unit as a fluorophore and o-phenylenediamine as a reactive site is constructed and excellent discrimination of o- Pab has been demonstrated to be due to the difference in highly reactive and bifunctional phosGene relative to its substitutes.

TL;DR: A highly selective fluorescent probe constructed through o-phenylenediamine covalently linking to coumarin (o-Pac), which can respond to phosgene in turn-on fluorescence mode, which exhibits good selectivity to phOSgene over triphosgenes and various acyl chlorides.

TL;DR: Two ratiometric two-photon probes, AcHS-1 andAcHS-2, which employ 4-amino-1,8-naphthalimide as the fluorophore and 4-azidobenzyl carbamate as the H2S response site exhibit high selectivity toward H2s over biothiols and other reactive species, low detection limits of 50-85 nM, low cytotoxicity, and high stability under physiological conditions.

TL;DR: A novel fluorescent probe for gold ions (Au (3+)/Au(+)) is reported through blocking photoinduced electron transfer, in which a boron dipyrromethene (Bodipy) derivative reveals high selectivity and sensitivity in a gold-catalyzed intramolecular hydroamination.

TL;DR: A ratiometric fluorescent chemosensor, Phos-1, was constructed with 4,5-diaminonaphthalimide as a fluorophore for selective and visual detection of phosgene.
