TLDR
In this article, a series of terminally substituted alkyl thiols, X(CH 2 ) 15 SH (X=CH 3, CH 2 OH, CO 2 H, CO2 CH 3, and CONH 2 ), have been prepared by adsorption from solution onto evaporated gold substrates.Abstract:
Monolayers of a series of terminally substituted alkyl thiols, X(CH 2 ) 15 SH (X=CH 3 , CH 2 OH, CO 2 H, CO 2 CH 3 , and CONH 2 ), have been prepared by adsorption from solution onto evaporated gold substrates. The structures habe been characterized by infrared (IR) spectroscopy, X-ray photoelectron spectroscopy (XPS), ellipsometry, and temperature-programmed desorption (TPD). The IR data shows the monolayer films to be densely packed, crystalline-like structures with all-trans conformation alkyl chains exhibiting average tilt angles of the chain axis in a range of 28-40° from the surface normal and an approximate 55° twist of the chain axis away from a configuration with the CCC plane perpendicular to the surface planeread more

Formation and Structure of Self-Assembled Monolayers.
TL;DR: Monolayers of alkanethiolates on gold are probably the most studied SAMs to date and offer the needed design flexibility, both at the individual molecular and at the material levels, and offer a vehicle for investigation of specific interactions at interfaces, and of the effect of increasing molecular complexity on the structure and stability of two-dimensional assemblies.

Structure and growth of self-assembling monolayers
TL;DR: In this article, the structural phases and the growth of self-assembled monolayers (SAMs) are reviewed from a surface science perspective, with emphasis on simple model systems, and a summary of the techniques used for the study of SAMs is given.

Self-assembled organic monolayers: model systems for studying adsorption of proteins at surfaces
TL;DR: Self-assembled monolayers of omega-functionalized long-chain alkanethiolates on gold films are excellent model systems with which to study the interactions of proteins with organic surfaces and the ability to create interfaces with similar structures and well-defined compositions should make it possible to test hypotheses concerning protein adsorption.

TL;DR: The mean size of the gold core in the synthesis of dodecanethiolate-stabilized Au cluster compounds can be finely adjusted by choice of the Au:dodecanETHiolate ratio and the temperature and rate at which the reduction is conducted as mentioned in this paper.
