On the morning of September 30, 2022, Professor Xu Huaping from the Department of Chemistry of Tsinghua University was invited by Professor Huang Hui to give a lecture on "Dynamically Responsive Selenium/Tellurium Containing Polymers" at the University of Chinese Academy of Sciences (UCAS) in Room 208 of the First Teaching Building.

Selenium/tellurium-containing polymer materials have gained widespread attention in recent years due to their potential for applications in self-healing, shape memory, information storage, optical programming materials, and medical materials.

In his lecture, Prof. Huaping Xu gave a clear and organized introduction to the history of the development of selenium/tellurium-containing polymer materials. Firstly, the unique bond energy of C-Se bond determines its unique dynamic responsiveness. The team synthesized various Se containing polymer materials and found that these materials have unique dynamic responsiveness. Then atomic force microscopy was used to test the chain-breaking energy and explain why the Se containing polymer materials are dynamically responsive from the bond energy perspective. He also introduced the applications of Se/Tellurium-containing polymer materials in various fields such as self-healing, shape memory, information storage, optical programming materials, hydrophobic materials, and medical materials. Finally, Prof. Xu Huaping exchanged and discussed with the students and teachers on site, which received enthusiastic responses from them. 

       Huaping Xu, Professor, Department of Chemistry, Tsinghua University, China, received his B.S. and Ph.D. degrees in 2001 and 2006, respectively, from the School of Chemistry, Jilin University, China, under the supervision of academician X. Zhang, and spent a year of exchange study at KU Leuven, Belgium, from 2004 to 2005. He has been a professor in the Department of Chemistry, Tsinghua University since 2014, and was awarded the "Young Chemistry Award of the Chinese Chemical Society" in 2011 and the "Outstanding Young Scientist Fund" by the National Natural Science Foundation of China in 2014. He is an associate editor of ACS Biomaterials Science & Engineering and an editorial board member of ACS Macro Letters, Supramolecular Materials, and Chemical Education.
