Abstract
A simple chemical approach for the covalent assembly of organic molecules on silicon surfaces via robust linkages is provided. This is achieved by the efficient reaction between a nucleophilic functional group and a halogenated Si surface. The nucleophile anchor is the bridge between two surface Si atoms. The resulting organic layer is thermally stable. The method demonstrated herein is generally applicable for the assembly of a variety of functional organic molecules under vacuum environment or in solution phase.
