Major: Chemistry

Degree: Doctor of Philosophy

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.
