报告摘要：
It is well-established that strain arises in organic molecules as a result of non-ideal bond lengths, bond angles, and unfavorable non-bonded interactions. The constrained geometries of ring systems are particularly predisposed to creating strain. Our recent research balances strain relief and geometry constraint to “switch-on” dynamic processes. This talk will summarize our investigations1-3 of fluxional carbon cages, which can give rise to phenomena such as dynamic preferential crystallization and stimulus-responsive dynamic sp3-C stereochemistry .
It will also describe our discovery4–6 of an aromatic-to-nonaromatic that emerges when the aromatic stabilization energy of a ring system is offset precisely by steric strain (Figure 1b).
报告人简介：
Dr Paul McGonigal is Reader in Functional Organic Materials at the University of York, where he investigates dynamic processes in organic functional materials. His group’s research has been recognized by the the RSC Harrison Meldola Memorial Medal 2022 and the German Chemical Society’s Liebig Lectureship 2023. Paul received his undergraduate (MChem, 2007) and postgraduate (PhD, 2011) degrees from The University of Edinburgh, working under the direction of Prof David Leigh. In 2011, he moved to The Institute of Chemical Research of Catalonia (ICIQ), Spain, as a Postdoctoral Researcher in the laboratory of Prof Antonio Echavarren. The following year, he was awarded a US–UK Fulbright Scholarship to conduct research with Prof Fraser Stoddart’s research group at Northwestern University. From 2015–2023, Paul initiated his independent academic career at Durham University as an Assistant and Associate Professor. He currently holds an EPSRC Early Career Fellowship.
