Anwendungen
Verwenden(3-Mercaptopropyl)trimethoxysilane is used as a capping molecule for cadmium sulphide nanocrystals. It is used in the preparation of multi-walled carbon nanotubes and bilayer modified gold electrode. It acts as a linker molecule used in the preparation of gold multilayers and as a molecular adhesive in the fabrication of vapor-deposited gold electrodes on glass substrates. It is also used as a precursor for silica.
Darstellung
synthetische(3-Mercaptopropyl)trimethoxysilane was prepared by using thiourea and 3-chloropropyltrimethoxysilane as raw materials, petroleum ether as solvent, KI as catalyst, and ethylenediamine as neutraliser.
