| Functionalizing organic groups onto oxide-free, hydride-terminated porous silicon surfaces via hydrosilylation chemistry provides an effective route to intelligent interfacial design. Monolayers, bound through direct silicon-carbon bonds are produced via a number of wet, benchtop methods and protect the underlying silicon surface from ambient oxidation and chemical attack. In this preliminary study, alkyl monolayers were grafted onto porous silicon using microwave radiation, a quick and effective way of preparing monolayer protected porous silicon. Samples were functionalized with a variety of terminal groups via simple organic transformations on a terminal olefin monolayer. Monolayer preparation, transformation, and substrate oxidation were monitored via transmission mode Fourier transform infrared spectroscopy (FTIR). |
