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.

L'invention concerne une approche chimique simple de l'assemblage covalent de molécules organiques sur des surfaces en silicium par des liaisons robustes, ce qui est réalisé par une réaction efficace entre un groupe fonctionnel nucléophile et une surface Si halogénée. L'ancre nucléophile constitue la passerelle entre deux atomes Si de surface. La couche organique qui en résulte est thermiquement stable. Le procédé, selon l'invention, s'applique généralement à l'assemblage d'une variété de molécules organiques fonctionnelles dans un milieu sous vide ou en phase de solution.
