个人简介

Xingwei grew up at the foot of the Yanshan Mountains in Qinhuangdao and pursued his undergraduate studies at Hebei University of Technology. In 2007 he joined the group of Zhiping Li at Renmin University of China for his Master studies on iron-catalyzed radical reactions. In 2010 he went on to pursue his PhD in Physical Organic Chemistry from University (LMU) of Munich, Germany, under the supervision of Herbert Mayr, working on the kinetic and mechanistic studies of quinones. After graduating, he joined the group of Samir Z. Zard to study the radical chemistry of xanthates at École Polytechnique in France as a CNRS postdoctoral fellow (2014–2015). Then he moved to Oliver S. Wenger’s lab at the University of Basel in Switzerland as a NCCR postdoctoral fellow (2015–2019), where his work focused on photo-induced electron transfer and photocatalysis. In 2019 he started his independent career at Tsinghua University, where he is currently an Associate Professor of Chemistry.

研究领域

Radicals, i.e. molecules with an unpaired electron, are involved as short-lived intermediates in many chemical transformations. While radicals have already played an import role in organic synthesis and macromolecular chemistry for almost a century, recent decades have witnessed a hype in radical chemistry: Photocatalysis, organic electronics, atmospheric chemistry, and enzyme catalysis are just few examples of eminent current research activities. Electron Paramagnetic Resonance (EPR) is the most important method to investigate structure and reactivities of radicals. However, the presently available techniques either allow to detect radicals with high sensitivity (steady-state cw-EPR) or provide high time resolution. We have now developed a method, Ultrawide Single Sideband Phase-Sensitive Detection Time Resolved EPR (U-PSD TREPR), which combines both aspects and allows to detect radicals with an approximately two orders of magnitude higher sensitivity compared to conventional TREPR, without compromising time resolution. This new and universal method can be expected to open a new chapter in radical chemistry.
