The present invention describes a bioconjugation strategy and compounds that are useful therein in which a fluorescent signal is produced when two molecular or supramolecular entities are linked by chemoselective combination of one linker having an azido or halide substituent group with another linker having a cyano or an alkyne substituent group. A kit is also provided.

Copper(I)-catalyzed 1,3-dipolarcycloadditionreaction of nonfluorescent 3-azidocoumarins and terminal alkynes afforded intense fluorescent 1,2,3-triazole products. The mild condition of this reaction allowed us to construct a large library of pure fluorescent coumarin dyes. Since both azide and alkyne are quite inert to biological systems, this reaction has potential in bioconjugation and bioimaging
