Abstract

A newly developed spectrofluorometric method is based on the fabrication of an optical cyanopyridine derived sensor, 4-(6-diaryl)-2-oxo -1,2-dihydropyridine-3-carbonitrile using microwave irradiation. The fluorescence intensity of the proposed chemo sensor was obviously quenched in DMSO owing to the presence of UO22+ ions at λex/λem = 320/360 nm. The quenching effect of the cyano-derivative based sensor was found to be proportional to the concentration of UO22+ ion ranging between 9.60 × 10–9–5.28 × 10–5 mol L−1 with a detection and quantification limits of 1.71 × 10–11 and 5.2 × 10–11 mol L−1, respectively. © 2021, Akadémiai Kiadó, Budapest, Hungary.
