1,10-decanedithiol molecules are inserted into a n-decanethiol [CH@sub 3@(CH@sub 2@)@sub 9@SH] self-assembled monolayer (SAM) on Au{111} and are characterized by scanning tunneling micrsocopy (STM). Bifunctional molecules are inserted into the SAM for the covalent attachment of monolayer protected gold nanoparticles. The gold nanoparticles are synthesized with short chain alkylthiol ligands to promote covalent attachment to the inserted 1,10-decanedithiol molecules and to reduce the probability of steric binding. Electronic properties of isolated gold nanoparticles are compared to proximate pairs and assemblies of gold nanoparticles.
