Descrição geral

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.

Aplicação

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).

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

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
