Description

General description

2-Ethylhexanethiol is an organothiol that forms a self-assembled monolayer (SAM) on a variety of surfaces such as metal oxides and metals. It modifies the surface by acting as a corrosion inhibitor and increases the stability of the surface.

Application

2-Ethylhexanethiol can be used as a capping agent on the gold surface for the development of chemiresistive vapor sensors. It also forms a SAM on copper indium sulfide (CuInS₂) which can be used as an active layer on organic electronic devices such as organic light emitting diodes (OLEDs) and solar cells.
