Highly selective and sensitive near-infrared fluorescent sensors for cadmium in aqueous solution

Org Lett. 2011 Jan 21;13(2):264-7. doi: 10.1021/ol102692p. Epub 2010 Dec 8.

Abstract

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 Cd(2+) from other metal ions, especially the CYP-2, which can distinguish Cd(2+) in neutral buffer solution.
