Abstract

A zinc sensor based on quinoline and morpholine has been synthesized. The sensor selectively fluoresces in the presence of Zn^2 +, while not for other metal ions. Absorbance changes in the 350 nm region are observed when Zn^2 + binds, which binds in a 1:1 ratio. The sensor fluoresces due to Zn^2 + above pH values of 6.0 and in the biological important region. The Zn^2 +-sensor complex has the unique ability to detect both Hg^2 + and HS⁻. The fluorescence of the Zn^2 +-sensor complex is quenched when it is exposed to aqueous solutions of Hg^2 + with sub-micromolar detection levels for Hg^2 +. The fluorescence of the Zn^2 +-sensor complex is also quenched by aqueous solutions of hydrosulfide. The sensor was used to detect Zn^2 + and Hg^2 + in living cells.
