Biography

Qiong Wu is currently a postdoctoral researcher in Prof. Jeffrey Moore’s group. He received his Ph.D. in Macromolecular Science and Engineering from Case Western Reserve University in 2016 (advisor: Prof. Stuart Rowan) followed by postdoctoral research at the University of Chicago (2016-2018). He received his B.S. in Polymer Science and Engineering in 2009 and M.S. in Chemistry in 2011 (advisor: Prof. Gaoquan Shi), both from Tsinghua University, Beijing. His fields of research include organic synthesis, mechanophore design, molecular machines and mechanically interlocked molecules, supramolecular chemistry and electrochemical energy storage materials.

Honors

National Science and Technology Award of China (5th completer, 2016)
Scientific Research Achievement Award from the Ministry of Education of China for Science and Technology (4th completer, 2013)
Outstanding Master Graduate Award of Tsinghua University (2011)

Research

Qiong Wu’s current research is focused on the design and synthesis of new mechanophore systems for ultrasound-controlled drug releasing and chemiluminescence. Mechanophores that release small molecules (drugs, chemiluminescence motifs, etc.) from polymer networks show a wide range of attractive applications in materials science and biomedical engineering. Currently, molecular-releasing mechanophores either have low releasing efficiency or suffer from polymer network degradation due to chain scission. I designed a series of mechanically interlocked mechanophores that have the potential to efficiently kick-off small molecules through space via topological hinderance, while the polymer network structure remains intact. This project is on an early stage and I’m currently studying a proof-of-concept rotaxane mechanophore system. This novel system is potentially applicable to a variety of mechanophores, opening a door toward a new concept of mechanophore activation strategy.
