dc.description.abstractA zinc sensor based on quinoline and morpholine has been synthesized. The sensor selectively fluoresces in the presence of Zn2+, while not for other metal ions. Absorbance changes in the 350 nm region are observed when Zn2+ binds, which binds in a 1:1 ratio. The sensor fluoresces due to Zn2+ above pH values of 6.0 and in the biological important region. The Zn2k-sensor complex has the unique ability to detect both Hg2+ and HS. The fluorescence of the Zn2+-sensor complex is quenched when it is exposed to aqueous solutions of Hg2+ with sub-micromolar detection levels for Hg2+. The fluorescence of the Zn2+-sensor complex is also quenched by aqueous solutions of hydrosulfide. The sensor was used to detect Zn2+ and Hg2+ in living cells. 2017 Elsevier B.V.
