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).

We studied the concentration-dependent agglomeration of apolar nanoparticles in different solvents. Octanethiol-stabilized gold nanoparticles (AuNPs) in evaporating liquid droplets were observed in situ using small-angle X-ray scattering. Concurrent analysis of liquid volume and particle agglomeration provided time-dependent absolute concentrations of...

Subnanometer noble metal clusters have enormous potential, mainly for catalytic applications. Because a difference of only one atom may cause significant changes in their reactivity, a preparation method with atomic-level precision is essential. Although such a precision with enough scalability...

A method is described for the in situ growth of substrate-supported organized gold nanoparticles. Upon exposure to an aqueous solution of a gold salt and a mild reducing agent, the particle size can be significantly increased without any loss of...

1-Adamantanethiol (1-AD), an example in this spectrum of molecules with distinct chemical and physical properties, forms self-assembled monolayers (SAMs) on Au{111} that are displaceable when exposed to other thiolated molecules from solution, vapor, or contact due to weak intermolecular interactions in 1-AD SAMs.
Read MoreSelf-assembled monolayers (SAMs) have attracted enormous interest for a wide variety of applications in micro- and nano-technology. In this article, we compare the benefits of three different classes of SAM systems (alkylthiolates on gold).
