Abstract
The present invention is directed to a silicon substrate having a monolayer formed by an electrochemically-induced reaction between silicon hydride moieties on the silicon surface and optionally substituted alkynes covalently bound to the surface of the silicon substrate and to a method for electrochemically producing such a functionalized silicon substrate. The method of forming a covalently bound monolayer on a silicon surface comprises the steps of contacting the silicon surface with a C2-C24 alkyne and electrografting optionally substituted alkynes to the silicon surface.
Claims9
A method for forming a covalently bound monolayer of organic substituents on a silicon substrate having a surface comprising silicon hydride groups, said method comprising the steps of:
- contacting the surface of the silicon substrate with an electrically conductive, substantially oxygen-free, aprotic organic solvent solution comprising an optionally substituted C2-C24 alkyne;
- positioning a conductor electrode in electrical current flow communication with said solution;
- and
- applying an electrical potential to said solution between the silicon surface and the conductor electrode sufficient to induce electrical current flow through said solution between the silicon surface and the conductor electrode for a period of time sufficient to covalently bind at least a portion of the alkyne to the silicon surface.
