The formation of self-assembled one-dimensional molecular nanostructures on Si(100) is studied by scanning tunneling microscopy. Using the Ge-covered Si(100)-2×n surface as a tempting template, we have obtained large-scale one-dimensional styrene molecular nanostructures. The styrene molecules selectively bond to the Ge/Si(100)-2×n surface through the interactions between one C=C bond of the vinyl group and a Ge=Ge dimer to form C–Ge linkages via a [2+2] cycloaddition. This result may provide a pathway for forming controlled organic nanostructures on the Si(100) surfaces. © 2004 American Institute of Physics.
