An Organic Fluorescent Probe for Selective Picric Acid Detection: Experimental and Theoretical Investigations With Smartphone and Real‐Time Applications

Kushal Dubey, Akhilesh Kumar Singh

High‐precision optical sensing of picric acid (PA) is crucial due to its pronounced toxicity and explosive properties. PA possesses several distinctive physicochemical attributes, including strong proton donor‐acceptor functionality, an exceptionally low pK a , high electron deficiency and excellent aqueous solubility, which …
