Specific Detection of Picric Acid and Nitrite in Aqueous Medium Using Flexible Eu(III)-Based Luminescent Probe

Development of an effective method for the detection of picric acid (PA) in aqueous phase has attracted great attention. In this work, the luminescent probe Eu-1 involving a hexadentate 2-Amino- 3-phenylpropanol based ligand L was successfully ex-ploited for the selective detection of PA in presence of other nitro analytes in aqueous medium. The selective detection of PA and nitrite by Eu-1 was rationalized through DFT computational study.
