英文摘要	In this study, a novel coumarin-derived compound bearing the furan moiety called 7-diethylamino-3-formylcoumarin (2′-furan formyl) hydrazone (1) has been designed, synthesized and evaluated as a Zn2 + ratiometric fluorescent probe in ethanol-water system. This probe 1 showed good selectivity and high sensitivity towards Zn2 + over other metal ions investigated, and a decrease in fluorescence emission intensity at 511 nm accompanied by an enhancement in fluorescence emission intensity at 520 nm of this probe 1 was observed in the presence of Zn2 + in ethanol-water (V: V = 9: 1) solution, which provided ratiometric fluorescence detection of Zn2 +. Additionally, the ratiometric fluorescence response of 1 to Zn2 + was nearly completed within 0.5 min, which suggested that this probe 1 could be utilized for sensing and monitoring Zn2 + in environmental and biological systems for real-time detection. © 2016 Elsevier B.V.
