A method for the direct patterning of 1-alkynes onto hydrogen-terminated silicon is presented. It combines microcontact printing with illumination through the stamp, and results in the formation of an alkenyl monolayer. The formation of heterogeneous monolayers is demonstrated by subsequent backfilling. Direct patterning of 1-alkynes onto H-Si is enabled by combining microcontact printing with visible-light illumination through the stamp.
