Chem Commun (Camb). 2011 Nov 21;47(43):11963-5. doi: 10.1039/c1cc14963f. Epub 2011 Oct 3.

Abstract

A new type of fluorescent probe (1) with two triazole groups that are conjugated with a carbazole moiety was synthesized by a Cu(I)-catalyzed alkyne-azide click reaction for the selective and sensitive detection of cyanide via fluorescence enhancement by ligand exchange and metal ion removal.
