Thesis (Ph.D.)--The University of Wisconsin - Madison, 2012.

The ability to introduce specific molecular groups to the surfaces of semiconductors holds great promise in photovoltaics, catalysis, sensing, and molecular electronics. This thesis describes the covalent functionalization of ZnO and diamond surfaces with a variety of different organic, inorganic, and organometallic groups. The first part of this thesis investigates the photochemical grafting of organic alkenes on the (101-0) surface of single crystal ZnO and ZnO nanorods. The molecular layers are shown to be conformal to the underlying ZnO with a thickness controlled by the illumination time. The ability to perform multi-step synthetic chemistry on the ZnO surface is demonstrated. The second part of this thesis looks at the formation of redox-active diamond surfaces. A combination of photochemical grafting and click chemistry (copper catalyzed azide alkyne cycloaddition) is used to couple inorganic and organometallic complexes to the diamond surface. A model ruthenium complex [Ru(tpy)2] tethered to the surface demonstrates remarkable stability to potential cycling out to very strongly oxidizing potentials (1.5 V vs. NHE). The electron transfer rate between diamond electrodes and surface-tethered ferrocene is also measured using electrochemical impedance spectroscopy. The electron transfer rate is shown to decrease with increasing surface coverage but is found to be independent of chain length. Electron transfer rates are generally fast, typically 1,000-10,000 per second.
