ABSTRACT
Hg2+ in the environment endangers human health, and a convenient monitoring method is needed for the detection of Hg2+. In this study, we constructed a dual colorimetric near-infrared fluorescent probe (E)-2-(3-(3-(1,3-dithian-2-yl)-4-hydroxystyryl)-5,5-dimethylcyclohex-2-en-1-ylidene)malononitrile (YF-Hg), based on the malononitrile isophorone. YF-Hg can detect Hg2+ rapidly and sensitively, with fluorescence emission in the near-infrared region (659 nm) with an obvious color change from violet to red in the visible light range. In addition, the low toxicity and large Stokes shift (191 nm) of YF-Hg also suggest that it is a potential tool for live-cell fluorescence imaging.
