Highly Selective and Sensitive Near-Infrared Fluorescent Sensors for Cadmium in Aqueous Solution

On the basis of tricabocyanine, two near-infrared fluorescent sensors CYP-1 and CYP-2 have been designed and synthesized. Both of them can selectively and sensitively recognize Cd2+ from other metal ions, especially the CYP-2, which can distinguish Cd2+ in neutral buffer solution.
