DESCRIPTION:Abstract:\n\nThe C=N bond is a critical structural piece of man
 y N-donor ligand scaffolds and is central to the properties and reactivity
  of a number of important coordination complexes - for example\, promoting
  charge-transfer character in complexes of bipyridines (e.g.\, [Ru(bpy)3]2
 +) or the 'redox non-innocence” of a-diimine complexes. Benzannulation can
  extend the conjugated C=N containing p-system of pyridine to quinoline (2
 \,3-benzopyridine) to acridine (2\,3-benzoquinoline)\, stabilizing the low
 est unoccupied molecular orbital (LUMO) of the molecule and boosting elect
 ron-accepting properties\, but the positioning of the benzannulation matte
 rs. For example\, phenanthridine (3\,4-benzoquinoline)\, an asymmetric iso
 mer of acridine\, bears a similarly electronically accessible extended π-s
 ystem but more chemically isolated imine-like C=N moiety. In this presenta
 tion\, the impact of such site-selective π-extension on the chemistry and 
 properties of phenanthridine as a molecule and ligand will be discussed.\n
 \nBio:\n\n\n	Born and raised in North York\, Ontario\, Dave attended the Un
 iversity of King’s College/Dalhousie University in Halifax\, NS\, where he
  worked with Prof. Neil Burford on the coordination chemistry of polyphosp
 horus cations (B.Sc. Hons.\, Chemistry\, 2004). He then started graduate s
 chool at the University of Toronto (M.Sc.\, 2006) under the tutelage of Pr
 of. Ian Manners\, moving with Ian to the University of Bristol where he co
 mpleted his Ph.D. (2009)\, earning a Faculty of Science Commendation for h
 is thesis on metal-containing rings and polymers. Upon graduation\, Dave m
 oved to central Texas to work with Prof. Oleg V. Ozerov at Texas A&M Unive
 rsity on multi-nucleating pincer ligands and catalyst design\, learning X-
 ray crystallography along the way. In 2011\, Dave joined Prof. Theodor Aga
 pie’s group at Caltech\, where he divided his time between projects on bio
 inorganic model compounds and C-H functionalization. During his studies\, 
 Dave received several awards including the King’s Medal\, NSERC CGS/PGS Fe
 llowships\, and was a Camille & Henry Dreyfus Environmental Chemistry Fell
 ow at Caltech.\n	\n	In July 2013\, Dave began his independent career as an A
 ssistant Professor in the Chemistry Department at the University of Manito
 ba and was promoted to Associate Professor in 2019. He is currently a Facu
 lty of Science Research Chair in Fundamental Science (Physical Sciences) a
 nd runs a research group trying to address questions in sustainable chemis
 try\, materials and energy science using the tools of inorganic synthesis\
 , coordination chemistry and catalysis. \n
