Zach joined us for the summer after graduating from Alma College.  He is studying for his PhD in Inorganic Chemistry at Notre Dame University this fall.

Stability and Decomposition Pathways of Potential Redox Shuttles and Non-aqueous Catholytes

Zachary S. Lincoln, Adina Dumitrascu, Jason G. Gillmore, Thomas F. Guarr

The Organic Energy Storage Laboratory has prepared a variety of carbazole and phenothiazine derivatives as potential catholytes for non-aqueous redox flow batteries and as redox shuttles for lithium ion batteries.  Their stabilities, beyond reversible voltammograms, has not been assessed; nor have their potential decomposition pathways.  Using Ion-Trap Mass Spectrometry (ITMS), the decomposition of these compounds can be investigated.  Additionally, deuterium-labelled analogs were prepared and characterized by GC-MS, 1H and 13C NMR, and ITMS to confirm the decomposition pathways observed in protio derivatives.

It was a great summer, Zach.  Thanks for spending it with us and best wishes for your experience at Notre Dame.
