“…This and the results presented here suggest that the increased thiol adhesion Laiho and Leiro [20] and Himmelhaus [4] observed was a multilayer of copper (I) thiolate formed from the pre-existing oxide.…”

“…This is often observed in thiol layers and is due to unreacted thiol in or on the film. The small peak (doublet) to higher binding energy 168 eV is indicative of a sulfonate, and shows some of the thiol has become oxidised [4]. This species has been observed before on the surface of thiol films after they were exposed to the atmosphere [15].…”

“…Additionally they showed that the thiol layer becomes oxidized to the sulfonate slowly when exposed to the atmosphere (after removing it from the thiol solution). Laiho and Leiro [20] show that copper surfaces with initial oxide layers show higher thiol adsorption than a clean copper surface, they cite Himmelhaus et al [4] who suggest that there is a catalytic effect generating a denser monolayer. They also show that some oxide remains below the thiol film although most is reduced by the action of the thiol.…”

“…In this way it is often considered possible to treat copper surfaces with thiols to produce a functionalized, oxide-free, metal-organic interface. In practice some oxygen is usually left at the interface and there has been some speculation as to what form this might be in [4] and the layer seldom behaves as well as those on gold or even silver [5].…”

It is common to think of thiols as molecules that form self-assembled monolayers on gold or similar metals, they have also been used as corrosion inhibitors on copper and steel, but we show here that if the copper remains in thiol solution corrosion is accelerated and a thick layer of corrosion products with a very rough surface forms. The layer is superhydrophobic; repelling water so effectively that it rolls off leaving the surface completely dry. It is composed of a copper (I) thiolate complex and growth occurs quite rapidly under normal conditions. The film morphology depends upon the solvent and thiol used. The presence of organic amines in the solution leads to the formation of thinner layers by removing corrosion products into solution, allowing the removal of native oxide layers.

“…From the full width at half-maximum (FWHM) of the core photoemission line, they drew conclusions about the heterogeneous adsorption sites on both Au and Ag surfaces. Himmelhaus et al studied the adsorption kinetics of docosanethiolate monolayers on the Ag (111) surface using XPS and near-edge X-ray absorption fine structure [46]. They demonstrated a domain growth mechanism, where alkanethiolate molecules nucleate around the initial alkanethiolate islands.…”

A review of the fundamental aspects of chemisorbed self‐assembled monolayers (SAMs), as a tool for building complex molecular systems on solid surfaces, is presented. Using alkanethiols, SAMs, as model systems the self‐assembly, surface structures, and SAM stability under different experimental conditions are discussed. We also point out the characteristics of SAMs that make them suitable especially for building active micro‐ and nanostructured molecular systems on surfaces, and stress their limitations resulting from defects, contaminants, and disorder. Finally, we show examples of interfacial architectures drawn from supramolecular and covalent systems to illustrate the potential of SAMs as robust platforms for building functional 3D structures on solid substrates.
