研究领域

Actinide chemistry; Synthesis; Density Functional Theory; Group 11 chemistry

Our research is divided into three areas: 1) Structure, bonding, spectroscopy, and reactivity of actinide complexes, 2) Group 11 reactivity, and 3) Computational chemistry. 1) Actinide Chemistry We are interested in exploring the fundamental nature of actinide-ligand bonding with soft donor ligands such as S and Se. Soft donor ligands are relevant to separation methods as sulfur-based ligands have been shown to have more selectivity towards actinides over lanthanides. image1 Publications in this area: Inorg. Chem. 2013, 52, 10623 Eur. J. Inorg. Chem. 2013, 4050 (special issue on small molecule activation) Radiochim. Acta 2013, 101, 631 Dalton Trans. 2015, 43, in press (special issue on f-element chemistry) 2) Group 11 Chemistry Group 11 elements have importance as fluorescent probes, sensors, and biological systems. The reactivity of dinuclear group 11 complexes, especially with amidinate ligands, is being investigated to examine the luminescence, metallophilic interactions, and redox chemistry.
