General description

1-Octanethiol (OT) is C8 alkanethiol that forms self-assembled monolayer (SAM) on a variety of nanoparticles. It has a low flash point and low vapor pressure.

Application

OT can be used as a sulfur precursor for the preparation of shell for CdSe/CdS quantum dots. It forms ligands that help in enhancing the power efficiency of hetero-junction nanorod sensitized solar cells as it enhances the electron extraction from the nanorod and TiO2 interface. OT based stabilized coating on copper nanoparticles (CuNPs) may be used in the dispersion of these colloidal particles in different sample solutions. It can be used to improve charge injection by creating a monolayer on gold source-drain electrode surfaces for bottom-contact thin-film transistors (TFTs).
