Suzanne Cathleen Bart an American chemist who is a professor of inorganic chemistry at Purdue University. [1] Her group's research focuses on actinide organometallic chemistry, and especially the characterization of low-valent organouranium complexes, actinide complexes with redox-active ligands, [2] and discovery of new reactions that utilize these compounds. [3] Bart's research has applications in the development of carbon-neutral fuel sources and the remediation of polluted sites.

Early life and education

Bart was an undergraduate student at the University of Delaware, where she earned her B.S. in 2001 She moved to Cornell University for graduate studies, earning a master's degree in 2003 and a Ph.D. in 2006 working with Paul Chirik. Her doctoral research considered iron catalysts with redox-active ligands. [4] [5] [6] [7] After completing her graduate studies, Bart moved to the University of Erlangen–Nuremberg in Germany, where she worked a postdoctoral researcher with Karsten Meyer. [8]

Research and career

Bart began her independent career at Purdue University in 2008. [9] She is interested in the design of new fuels and development of strategies to remediate nuclear waste. She mainly considers actinide chemistry and the organometallic chemistry of depleted uranium and transuranic elements. [10] [11] Depleted uranium emits weak alpha particles with a long half-life, and has considerable potential in the activation of large substrates. [12]

Bart has developed redox-active ligands to transform biologically and industrially relevant small molecules. These ligands can store electrons in the π* orbitals of their conjugated backbone, which facilitates multi-electron redox chemistry. [13] Bart has shown that it is possible to synthesize low-valent uranium alkyls, which avoids the U(IV) state and one-electron (radical) chemistry, the latter of which is harder to synthetically control. [10] Alongside the identification of new chemical transformations, Bart is interested in the fundamentals of carbon-uranium chemical bonding, [14] and the development of efficient catalysts. [11] She has extensively utilized the tris(pyrazolyl)borate ligand. [10] [15]

In polymer chemistry, chain walking (CW) or chain running or chain migration is a mechanism that operates during some alkene polymerization reactions. CW can be also considered as a specific case of intermolecular chain transfer. This reaction gives rise to branched and hyperbranched/dendritic hydrocarbon polymers. This process is also characterized by accurate control of polymer architecture and topology. The extent of CW, displayed in the number of branches formed and positions of branches on the polymers are controlled by the choice of a catalyst. The potential applications of polymers formed by this reaction are diverse, from drug delivery to phase transfer agents, nanomaterials, and catalysis.

Metal-ligand cooperativity (MLC) is a mode of reactivity in which a metal and ligand of a complex are both involved in the bond breaking or bond formation of a substrate during the course of a reaction. This ligand is an actor ligand rather than a spectator, and the reaction is generally only deemed to contain MLC if the actor ligand is doing more than leaving to provide an open coordination site. MLC is also referred to as "metal-ligand bifunctional catalysis." Note that MLC is not to be confused with cooperative binding.

A molecular electron-reservoir complex is one of a class of redox-active systems which can store and transfer electrons stoichiometrically or catalytically without decomposition. The concept of electron-reservoir complexes was introduced by the work of French chemist, Didier Astruc. From Astruc's discoveries, a whole family of thermally stable, neutral, 19-electron iron(I) organometallic complexes were isolated and characterized, and found to have applications in redox catalysis and electrocatalysis. The following page is a reflection of the prototypal electron-reservoir complexes discovered by Didier Astruc.
