Descrição geral

1-Hexadecanethiol (HDT) is an alkanethiol that forms a self-assembled monolayer (SAM) by linking sulfur ions with the surface atoms. The methyl groups form a network with the aqueous phase that allows the formation of hydrophobic surfaces with low surface tension.[1]

Aplicação

HDT functionalized gold surfaces[2][3] with pentacene form a low injection barrier, which can be used to enhance the performance of pentacene organic field effect transistors (OFETs).[4] It can also be used to immobilize silver nanoparticles (AgNPs), synthesized by reducing silver phosphine precursors.[5]
Used to prepare thiol-functionalized 1.5 nm gold nanoparticles via a ligand exchange process with triphenylphosphine-stabilized nanoparticles.[6] Used in the formation of hydrophobic SAMs. Due to the length of the alkane chain, the resulting monolayer is highly ordered.[7]

A versatile, facile, energy-saving, low-cost and plant-inspired self-assembly strategy was used to prepare super-hydrophobic coating in this study. Concretely, an appealing super-hydrophobicity surface was obtained by designing a molecular building block phytic acid (PA)-Fe (III) complex to anchor the substrate
