Abstract

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.

Semiconductor nanocrystals covalently bound to metal surfaces with self-assembled monolayers

Journal Article Colvin, V.L.; Goldstein, A.N.; Alivisatos, A.P. [Lawrence Berkeley National Lab., CA (United States)] - Journal of the American Chemical Society

A method is described for attaching semiconductor nanocrystals to metal surfaces using self-assembled difunctional organic monolayers as bridge compounds. Three different techniques are presented. Two rely on the formation of self-assembled monolayers on gold and aluminum in which the exposed tail groups are thiols. When exposed to heptane solutions of cadmium-rich nanocrystals, these free thiols bind the cadmium and anchor it to the surface. The third technique attaches nanocrystals already coated with carboxylic acids to freshly cleaned aluminum. The nanocrystals, before deposition on the metals, were characterized by ultraviolet-visible spectroscopy, X-ray powder diffraction, resonance Raman scattering, transmission electron microscopy (TEM),more »« less

Formation of metal clusters on the surfaces of covalently bound self-assembled ligand monolayers

Journal Article Li, D.; Moore, L.W.; Swanson, B.I. (Los Alamos National Lab., NM (United States)) - Langmuir; (United States)

This paper describes interactions between metal complexes and self-assemblies of covalently bound ligand monolayers on surfaces. Covalently bound molecular self-assemblies of (3-cyanopropyl)trichlorosilane (CPTS) were anchored on the surfaces of fused quartz and the native oxide of the [l angle]100[r angle] crystallographic orientation of p-doped Si wafers. The formations of a number of ruthenium and osmium metal carbonyl complexes on both the substrates and substrates coated with ligand monolayers have been examined with polarized variable-angle internal attenuated total reflection infrared spectroscopy (PVAI-ATR-IR). Both mononuclear species M(CO)[sub n]L (n = 2, 3), where L, = -(CH[sub 2])[sub 3]CN, and multinuclear species M[submore »« less

Self assembled molecular monolayers on high surface area materials as molecular getters

Patent King, David E. (Lakewood, CO); Herdt, Gregory C. (Denver, CO); Czanderna, Alvin W. (Denver, CO)

The present invention relates to a gettering material that may be used as a filtration medium to remove pollutants from the environment. The gettering material comprises a high surface area material having a metal surface that chemically bonds n-alkanethiols in an organized manner thereby forming a molecular monolayer over the metal surface. The n-alkanethiols have a free functional group that interacts with the environment thereby binding specific pollutants that may be present. The gettering material may be exposed to streams of air in heating, ventilation, and air conditioning systems or streams of water to remove specific pollutants from either medium.

Backfilled, self-assembled monolayers and methods of making same

Patent Fryxell, Glen E [Kennewick, WA]; Zemanian, Thomas S [Richland, WA]; Addleman, R Shane [Benton City, WA]; ...

Backfilled, self-assembled monolayers and methods of making the same are disclosed. The self-assembled monolayer comprises at least one functional organosilane species and a substantially random dispersion of at least one backfilling organosilane species among the functional organosilane species, wherein the functional and backfilling organosilane species have been sequentially deposited on a substrate. The method comprises depositing sequentially a first organosilane species followed by a backfilling organosilane species, and employing a relaxation agent before or during deposition of the backfilling organosilane species, wherein the first and backfilling organosilane species are substantially randomly dispersed on a substrate.
