Description

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.[1]

Application

HDT functionalized gold surfaces[2][3] with pentacene form a low injection barrier, which can be used to enhance the performance of pentacene organic field effect transistors (OFETs).[4] It can also be used to immobilize silver nanoparticles (AgNPs), synthesized by reducing silver phosphine precursors.[5]

Used to prepare thiol-functionalized 1.5 nm gold nanoparticles via a ligand exchange process with triphenylphosphine-stabilized nanoparticles.[6] Used in the formation of hydrophobic SAMs. Due to the length of the alkane chain, the resulting monolayer is highly ordered.[7]
