Diethyl 2,2'-(2-oxo-2-(quinolin-8-ylamino)ethylazanediyl) diacetate (DOQED), an aminoquinoline-based fluorescent probe, was synthesized, and successfully applied in detection of Cu2+ and S2- in an aqueous buffered solution. The emission signal of DOQED was selectively quenched by Cu2+, and was exclusively recovered by subsequent addition of S2-. The formation of a [Cu(DOQED)](2+) complex was confirmed by X-ray crystallography. (C) 2013 Elsevier B.V. All rights reserved.
