Self-assembled monolayers (SAMs) of long-chain alkylthiols on gold, silver and copper (bound as surface thiolates) and of fatty acids (bound as carboxy-lates to surface oxides) on silver, copper and aluminium produced well-... 

Hexadecanethiol monolayers also self-assemble on mercury surfaces and provide an extremely low defect density . Alkanethiols can likewise be assembled on GaAs (100) surfaces and can act as a useful semiconductor. Alkaneni-triles bind side-on (= x ) to gold and copper surfaces. The infrared signal in the range of 2000-2500 cm Ms replaced by a 1570-1630 cm band which is close to x -coordinated nitrile on platinum. Molecular dynamics calculations for —SH and —SCF13 on gold produced two chemisorption modes very close in energy . 

Another application of the EA method was to determine the shift in the work function of a metal (and the consequent Schottky barrier shift when used as a contact in diodes) that can be induced by self-assembled monolayers (SAMs) [69,70,146-148]. The metal work function can be controlled by attaching a monolayer of polar molecules to the surface of the metal. Because of the inherent ordering of the monolayers (especially for thiol-based adsorbates on copper gold or silver electrodes), the molecular dipoles are oriented relative to...

Summary. Self-assembled monolayers of alkanethiolates on surfaces of gold, silver, and copper have helped to illustrate differences in the chemistry of these surfaces and have clarified the relationship between the structure of a monolayer and its wetting properties (75,25). We are presently examining other ligands and substrates to identify surface coordination chemistries that will lead to new self-assembling systems (36). One of the goals of this project is to apply the differences between the coordination...

Interest in these studies arises from fundamental research where monolayers serve as models of biomimetic systems, as well as from important apphcations of such systems in molecular and bioelectronic devices, in sensors construchons, corrosion/inhibition phenomena, and synthesis of nanostructures ]93]. Although self-assembly processes of sulfur-containing compounds occur at the surfaces of many metals, especially the copper-group metals (Cu, Ag, Au), the most extensive studies have been... 

An alternative approach to formation of gold-thiol multilayers utilizes inorganic chemistry. Copper(II) carboxylate groups can be generated on the monolayer surface by treatment of the acid-terminated layer with the solution of a copper salt. The copper(II) ions have strong affinity for sulphur(II) compounds, and thiols self-assemble on top of this Cu-terminated film (equation 17)360.361.
