Studies on Coordination and Fluorescence Behaviors of a Novel Uranyl Ion-Selective Chemosensor Bearing Diaza 18-Crown-6 Ether and Naphthalimide Moieties

Abstract

To avoid environmental and biological impacts linked to uranium-contaminating solutions, the development of sensitive and selective uranium detection techniques for solutions has become a critical issue. Although various kinds of detection methodologies have been developed, they are still not totally satisfactory in terms of simplicity, efficiency, and versatility. In this work, a novel chemosensor bearing a diaza-18-crown-6 ether and two naphthalimides (PN-DCE) was synthesized for simple, selective, rapid, and cost-effective detection of uranyl ions (UO 2 2+ ) and characterized by 1 H-, 13 C-NMR, FT-IR, ESI-TOF-MS, and elemental analysis.

Experimental and theoretical study of novel aminobenzamide–aminonaphthalimide fluorescent dyads with a FRET mechanism

“…Anbu and coworkers developed a new naphthalimide–phenanthroimidazole fluorescent chemosensor for a turn-ON Cu 2+ detection in living cancer cells, 10 and a naphthalimide-aza 18-crown-6 ether ion-selective chemosensor for UO 2 2+ ion was reported by Tsukahara. 11 A ratiometric 4-amido-1,8-naphthalimide fluorescent sensor based on excimer-monomer emission for determination of pH and water content in organic solvents was reported by Bojinov and coworkers. 12 Zhang and coworkers developed a novel naphthalimide–glutathione chemosensor for fluorescent detection of Fe 3+ and Hg 2+ in aqueous medium 13 and the green synthesis of fluorescent N , O -chelating hydrazone Schiff base for multi-analyte sensing in Cu 2+ , F − and CN − ions was reported by Ervithayasuporn.…”
