Welcome to the Emslie Group Webpage

Research in the Emslie group is focused on:

(1) Highly rigid ligand actinide complexes: organometallic reactivity and catalysis, small molecule activation, redox chemistry, structural and bonding studies. Future work may also include applications in lanthanide/actinide separation.

(2) Late transition metal ambiphilic ligand complexes; synthesis, structures, stoichiometric reactivity, and catalysis.

(3) The development of new organometallic reactivity for metal Atomic Layer Deposition (ALD): new volatile precursor synthesis, solution deposition reactions, mechanistic studies, and ALD reactor studies.

As a consequence, the Emslie research program (as a whole) involves early and late transition metal, actinide and main group chemistry, coordination, organometallic and materials chemistry, organic ligand synthesis, catalysis, small molecule activation and ALD. The breadth of research carried out in the group provides students/PDFs with a uniquely broad background and skillset. Students interested in joining the group typically have a choice between several different research areas, which can differ significantly (e.g. more exploratory vs more applied research, substantial vs minimal new ligand synthesis, mainly organometallic vs coordination chemistry, transition metal vs f-element chemistry etc.). However, the Emslie group is a synthetic inorganic chemistry group, so the major focus (typically >80%) of all projects is molecular synthesis (mostly air-sensitive; in some cases extremely air-sensitive).

All aspects of our research program involve extremely air sensitive materials, and students/PDFs gain extensive expertise in the vacuum line and glove box techniques. These skills have wide academic and industrial application, for example in laboratories involved in homogeneous catalysis (e.g. olefin polymerisation or pharmaceutical synthesis), in semiconductor and microelectronics research, and in the nuclear industry. For more information on specialized glove box applications, see: http://www.mbraunusa.com/mbraun-glovebox-applications.htm.

Chemistry in the Emslie lab also relies heavily on the synthesis of new ligands (often containing B, Al, P, S, etc.) which requires a significant level of skill in organic synthesis and provides students with experience in techniques of importance in most chemistry laboratories.

Members of the Emslie group run and interpret data from a wide variety of techniques including: 1D, 2D, multinuclear and VT NMR spectroscopy, IR, NIR and UV-Vis spectroscopy, ALD reactor studies, GC-MS, HRMS, TGA, electrochemistry, and combustion elemental analysis. Students in the group also have the option to solve their own X­ray crystal structures and perform DFT calculations. Overall, this experience provides students/PDFs with the skills required to identify and study almost any molecular compound.
