In this paper, self-assembled monolayers (SAMs) derived from adsorption of nalkanethiols onto the surfaces of copper slow the oxidation of the copper surface by reaction with atmospheric dioxygen.Abstract:
Self-assembled monolayers (SAMs) derived from adsorption of n-alkanethiols onto the surfaces of copper slow the oxidation of the copper surface by reaction with atmospheric dioxygen. Angstrom-level changes in the thickness of the monolayer result in readily observable differences (by X-ray photoelectron spectroscopy, XPS) in the rates of oxidation of the copper and adsorbed thiolates. The rates of oxidation of the copper and the thiolates can be decreased by ∼50% by increasing the length of the adsorbate, and thus of the SAM, by four CH 2 unitsread more

Patterned self-assembled monolayers of alkanethiols on copper nanomembranes by submerged laser ablation
TL;DR: In this article, the authors demonstrate that submerged laser ablation (SLAB) is well-suited for this purpose, as thiols are exchanged in-situ, avoiding air exposition.
