    Abstract – Surface hydroxyl groups of indium tin oxide (ITO) react with zirconium or tin alkoxides to give surface metal alkoxide complexes, which can be converted to surface metallic complexes of carboxylates or phenoxides. These latter surface complexes can be used to modify electrode properties of the ITO.

    Abstract – Surface-bound complexes of zirconium, titanium, or tin were prepared on hydroxylated aluminum metal in either ultrahigh vacuum (UHV) or under near ambient conditions. Ligand metathetical reactions were performed on these complexes using phenols or carboxylic acids. Reactions were monitored by FT-IR, X-ray photoelectron spectroscopy and temperature programmed desorption in UHV, and by FT-IR and quartz crystal microbalance measurements under near ambient conditions. Ester adducts of surface tin and zirconium alkoxides were observed in UHV, and a tin transesterification catalyst was prepared based on these observations.

    Abstract – The relative ordering of the three sublevels of the phosphorescent triplet state of 2-indanone was determined by correlating optically detected magnetic resonance (ODMR) spectra taken with the sample in a Zeeman field with calculated spectra. Spin coherence was observed in the phosphorescent triplet state of 2-indanone in neat and doped single crystals by conventional and real time detection. The Hahn electron spin-echo signal was observed in real time by a pulse sequence which terminates with a continuous-wave low power field (LPF). The Fourier transform of the echo decay as a function of yielded a peak at 9.0 MHz which was attributed by isotopic substitution studies to nuclear coupling of the triplet electrons via the -protons in the molecule. Dephasing of the Hahn and stimulated spin echo in 2-indanone due to energy trapping was measured with chemically mixed crystals of 2-indanone prepared with varying concentrations of quinoxaline. Energy transfer to quinoxaline which served as a deep trap contributed to the dephasing of the echo.

    Abstract – The thermal decomposition profile for the product of organometallic chemical vapor deposition (OMCVD) of tetra(tert-butoxy)zirconium on an oxide-modified aluminum surface depends on the initial surface hydroxyl group coverage. Controlled thermolysis of the tri(tert-butoxy)zirconium species bound to the low hydroxyl group content surface shows nearly complete degradation to ZrO2 at T > 350 K. In contrast, thermolysis of the tri(tert-butoxy)zirconium species bound to the hydroxyl group-saturated surface gives a thermally more stable (to >450 K) di(tert-butoxy)zirconium surface complex. Deposition and thermal evolution reactions were followed by both reflection-absorption infrared and X-ray photoelectron spectroscopic.
