A thio-urea based chromogenic and fluorogenic chemosensor for expeditious detection of Cu2+, Hg2+ and Ag+ ions in aqueous medium

A thio-urea based chromogenic and fluorogenic chemosensor for expeditious detection of Cu2+, Hg2+... A novelsimple reversible fluorescent and colorimetric multiple metal ions chemosensor, 1-(4-(pyridine-4-yl) benzylidene) thiosemicarbazide (L), based on the thiourea group has been designed and synthesized. The chemosensor L successfully detect Cu2+, Hg2+ and Ag+ based on binding site-signalling approach. The detection limit reaches up to 10.67, 11.14 and 8.54 μM for Cu2+, Hg2+ and Ag+ ions respectively. L has been successfully applied for the determination of Cu2+, Hg2+ and Ag+ ions in real water samples. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Photochemistry and Photobiology A: Chemistry Elsevier

Abstract

A novelsimple reversible fluorescent and colorimetric multiple metal ions chemosensor, 1-(4-(pyridine-4-yl) benzylidene) thiosemicarbazide (L), based on the thiourea group has been designed and synthesized. The chemosensor L successfully detect Cu2+, Hg2+ and Ag+ based on binding site-signalling approach. The detection limit reaches up to 10.67, 11.14 and 8.54 μM for Cu2+, Hg2+ and Ag+ ions respectively. L has been successfully applied for the determination of Cu2+, Hg2+ and Ag+ ions in real water samples.
