Local reactions are triggered by delivering molecules from an atomic force microscope (AFM) tip, allowing for direct modification of surfaces with a chemical functionality of interest. We synthesized silicon wafer-bound acetylene moieties which readily undergo 1,3-dipolar cycloaddition with azide moieties delivered from an AFM tip to form 1,4-disubstituted 1,2,3-triazoles. This selective and robust technique allows for the creation of multiple, different lithographed features of submicron dimensions on a surface.
