Abstract

A dual-function chemosensor for Hg 2 and Zn 2 ions, inspired by the green fluorescent protein (GFP) chromophore, was designed and synthesized, which could specifically recognize Zn 2 through an "OFF-ON" fluorescence mechanism due to the restriction of the free rotation of the aryl-alkene bond, whilst also producing a selective visible colorimetric response from yellow to pink with Hg 2 ions. The response upon exposure to Zn 2 and Hg 2 is instantaneous, and the detect limits of Zn 2 and Hg 2 are 2.18×10 -8 M and 4.91×10 -7 M respectively.
