Beschreibung

Allgemeine Beschreibung

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.[1][2]

Anwendung

1-Hexanethiol can be mixed with 4-mercaptophenol to functionalize gold nanoparticles (AuNPs) for use as chemi-resistive sensors.[3] It can also form a protective coating against oxidative reactions and contaminating layers on copper surfaces.[2] It can also be used as a thiol based ligand which finds potential application as a semiconducting material in thin film solar cells.[4]
It is used to tune the electrical characteristics in networked carbon nanotube field-effect transistors.[5] 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.[6]
