General description

1-Nonanethiol is an alkanethiol, a stabilizer that forms a self-assembled monolayer (SAM) on a variety of substrates. It is used as a thiol based protective coating.

Application

1-Nonanethiol is mainly used to form self-organized monolayers on gold, mercury, silver and platinum surfaces. These monolayers functionalize the surface atoms and improve the surface property of the composite.

Developing a clearer understanding of electron tunneling through molecules is a central challenge in molecular electronics. Here we demonstrate the use of mechanical stretching to distinguish orbital pathways that facilitate tunneling in molecular junctions. Our experiments employ junctions based on
