General description

1-Hexanethiol is an organothiol that forms a self-assembled monolayer (SAM) on a variety of nanoparticles. It consists of S head group, CH2 alkane chain, and CH3 terminal group.

Application

1-Hexanethiol can be mixed with 4-mercaptophenol to functionalize gold nanoparticles (AuNPs) for use as chemi-resistive sensors. It can also form a protective coating against oxidative reactions and contaminating layers on copper surfaces. It can also be used as a thiol based ligand which finds potential application as a semiconducting material in thin film solar cells.
It is used to tune the electrical characteristics in networked carbon nanotube field-effect transistors. It is also used as a monolayer on copper surfaces to retard surface oxidation during exposure to the environment which can then be desorbed effectively with an annealing step in inert N2 to provide a clean Cu surface.
