General description

1-Hexadecanethiol (HDT) is an alkanethiol that forms a self-assembled monolayer (SAM) by linking sulfur ions with the surface atoms. The methyl groups form a network with the aqueous phase that allows the formation of hydrophobic surfaces with low surface tension.

Application

Used to prepare thiol-functionalized 1.5 nm gold nanoparticles via a ligand exchange process with triphenylphosphine-stabilized nanoparticles. Used in the formation of hydrophobic SAMs. Due to the length of the alkane chain, the resulting monolayer is highly ordered.
HDT functionalized gold surfaces with pentacene form a low injection barrier, which can be used to enhance the performance of pentacene organic field effect transistors (OFETs). It can also be used to immobilize silver nanoparticles (AgNPs), synthesized by reducing silver phosphine precursors.
