Usage

General Description

(1-Mercaptoundec-11-yl)hexa(ethylene glycol) is a chemical compound that contains a mercaptan group and a polyethylene glycol chain. The mercaptan group is a thiol, which means it contains a sulfur atom bonded to a hydrogen atom, and it is often used in the production of rubber and plastic polymers. The polyethylene glycol chain is a polymer of ethylene oxide, and it is commonly used as a surfactant, emulsifier, and solvent in various industrial and consumer products. The combination of these two components in the compound makes it a versatile chemical that can be used in a wide range of applications, including as a component in personal care products, pharmaceuticals, and industrial processes.

Formation of self-assembled monolayers by chemisorption of derivatives of oligo(ethylene glycol) of structure HS(CH2)11(OCH2CH2)mOH on gold

This paper describes the preparation of oligo(ethylene glycol)-terminated alkanethiols having structure HS-(CH2)11(OCH2CH2)mOH (m = 3-7) and their use in the formation of self-assembled monolayers (SAMs) on gold. A combination of experimental evidence derived from X-ray photoelectron spectroscopy (XPS), measurement of contact angles, and ellipsometry implies substantial disorder in the oligo(ethylene glycol)-containing segment. The order in the -(CH2)11- group is not denned by the available evidence. The SAMs are moderately hydrophilic: θa(H2O) = 34-38°; θr(H2O) = 22-25°. A study of monolayers containing mixtures of HS(CH2)11CH3 and HS(CH2)11(OCH2CH2)6OH suggests that the oligo(ethylene glycol) moieties are effective at preventing underlying methylene groups from influencing wetting by water. A limited study demonstrates that these oligo(ethylene glycol)-containing SAMs resist the adsorption of protein from solution and suggests that SAMs will be a useful model system for studying the adsorption of proteins onto organic surfaces.
