β-Diketones are well known to form metal complexes with practically every known metal and metalloid. Metal complexes of fluorinated β-diketones generally exhibit increased volatility and thermal stability compared to the non-fluorinated analogues, and thus are used extensively in various chemical vapor deposition (CVD) processes for the deposition of metal, simple or mixed metal oxides, and fluorine-doped metal oxide thin films. Furthermore, the electron-withdrawing nature of the fluorinated ligand enhances the Lewis acidity of a coordinatively unsaturated metal center which facilitates additional coordination reactions. The physical and structural properties of fluorinated β-diketonate complexes are discussed in Chapter 1 …

There is a considerable interest in the use of metal oxides for development of novel high-technological materials such as gas sensors, multiferroics, and electrocatalysts. In particular, the design of complex oxides, which incorporate more than one type of metal atom, is focused on enriching chemical and physical properties of the target materials and allowing for increased functionality. In order to replace the harsh conditions associated with traditional synthetic routes that often require high temperatures and/or pressures, new soft chemistry methods for the preparation of mixed-metal oxide materials have been developed. One of the most promising directions is the emergence of …

Developing Dimetal Paddlewheel Complexes For Catalytic Applications, Margaret E. Napier
Legacy Theses & Dissertations (2009 - 2024)
Although there are countless examples of rhodium-catalyzed organic reactions in the chemical literature, the field continues to develop at a steady pace, as focus shifts taking advantage of economy of resources while maintaining efficiency of the catalytic reactions. The work presented is separated into three chapters, with each describing a specific approach to the development of new materials which can provide either a direct economy of resources and reagents or can be used for heterogenization of catalytic systems.
Bowl-Shaped Polyaromatic Hydrocarbons (Buckybowls) : Crystal Packing And Metal Binding Reactions, Alexander S. Filatov
Bowl-Shaped Polyaromatic Hydrocarbons (Buckybowls) : Crystal Packing And Metal Binding Reactions, Alexander S. Filatov
Legacy Theses & Dissertations (2009 - 2024)
This work is a part of a broad program in our laboratory dedicated to the investigation of a new class of non-planar polyaromatic hydrocarbons that map onto the surfaces of fullerenes (and referred to as buckybowls). It focuses on the preparation of buckybowls, their molecular and solid state structures, and reactivity in metal binding reactions. For the first time, the structures of all available buckybowls have been analyzed using X-ray diffraction data collected in the course of this work, as well as data previously obtained in our group or reported by others (and dearchived from the Cambridge Structural Database). Forces …
