Abstract
- A new Zn2+ selective chemosensor (3) was synthesized by condensation of commercially available substituted salicylaldehyde and isonicotinohydrazide, and characterized by single crystal X-ray crystallography. Receptor 3 with Zn2+ exhibited a highly selective and pronounced enhancement in the fluorescence emission among different cations by forming a 2:1 complex. The receptor can detect Zn2+ up to nanomolar level (6.75nM) with good tolerance of other metal ions and can be used for in vitro cellular imaging. [ABSTRACT FROM AUTHOR]
