Methods are described for attaching semiconductor nanocrystals to solid inorganic surfaces, using self-assembled bifunctional organic monolayers as bridge compounds. Two different techniques are presented. One relies on the formation of self-assembled monolayers on these surfaces. When exposed to solutions of nanocrystals, these bridge compounds bind the crystals and anchor them to the surface. The second technique attaches nanocrystals already coated with bridge compounds to the surfaces. Analyses indicate the presence of quantum confined clusters on the surfaces at the nanolayer level. These materials allow electron spectroscopies to be completed on condensed phase clusters, and represent a first step towards synthesis of an organized assembly of clusters. These new products are also disclosed.

[ What is claimed is:] [1.] A semiconductor assembly comprising:a) a solid inorganic substrate surface;b) a self-assembled monolayer of heterobifunctional bridging moieties covalently bonded thereto, each of said bridging moieties having two functional groups, with one of said functional groups covalently bonded to said substrate surface; andc) semiconductor nanocrystals covalently bonded to said bridging moieties through a second of said two functional groups on each of said bridging moieties.
