Abstract

The present invention includes a composition comprising an alkyne-based substrate, an azide-based substrate, a Cu(II) salt and a photoinducible reducing agent. The present invention further includes a method of immobilizing a chemical structure in a given pattern onto a section of the surface of a solid substrate, using the photoinducible Cu(I)-catalyzed azide-alkyne cycloaddition Click reaction.
