Functionalization of Acetylene-Terminated Monolayers on Si(100) Surfaces: A Click Chemistry Approach

In this article, we report the functionalization of alkyne-terminated alkyl monolayers on Si(100) using “click” chemistry, specifically, the Cu(I)-catalyzed Huisgen 1,3-dipolar cycloaddition reaction of azides with surface-bound alkynes. Covalently immobilized, structurally well-defined acetylene-terminated organic monolayers were prepared from a commercially available terminal diyne species using a one-step hydrosilylation procedure.
