UNLV Theses, Dissertations, Professional Papers, and Capstones

Rare-earth elements include the lanthanide series in the periodic table with the addition of scandium and yttrium. China produces approximately 95% of the world’s rare-earths supply and is the largest consumer of the world’s rare earth supply. Domestic production of rare-earth metals is a priority in the US. The domestic demand for rare-earth elements is largely based on their use in electronic devices, catalytic converters, and more importantly defense applications. Therefore, China’s monopoly of rare-earth elements is viewed as a threat to national security. Although capital investments have resulted in an increase in domestic mining and refining of rare-earth materials, …

Research projects described in this dissertation are focused on studying the physicochemical properties, including the photochemical, redox, and magnetic properties, of LnII-containing cryptates and how ligand structure influences metal–ligand interactions that in turn influence physicochemical properties. The results of these studies enable tailoring of the coordination properties of metal complexes that are important in applications including luminescent materials, chemical reductions, catalysis, and imaging.
