Nanocrystal gold molecules

TLDR
In this article, a series of gold nanocrystals, passivated by self-assembled monolayers (SAMs) of straight-chain alkylthiolate molecules (RS, R) are described.
Abstract
The creation of perfect nanometer-scale crystallites (nanocrystals), identically replicated in unlimited quantities, in a state that can be manipulated and understood as pure macromolecular substances, is an ultimate challenge of modern materials research with outstanding fundamental and potential technological consequences.[’l We report on the prediction, isolation, and characterization of a series of gold nanocrystals, passivated by self-assembled monolayers (SAMs) of straight-chain alkylthiolate molecules (RS, R
