个人简介：

Wei Zhang received his B.S. in Chemistry from Peking University in 2000, and his Ph.D. in Chemistry from University of Illinois at Urbana-Champaign (UIUC) (with Prof. Jeffrey Moore) in 2005. After a postdoc stint at MIT (with Prof. Timothy Swager), he started his independent career at the Department of Chemistry and Biochemistry at University of Colorado, Boulder in 2008, and was promoted to Associate and Full Professor with tenure in 2014 and 2018, respectively. His research is focused on utilizing dynamic covalent chemistry to develop novel organic or hybrid functional materials targeting a broad range of environmental, energy and biological applications, such as carbon capture, molecular separation, nanocomposite fabrication, energy storage, and self-healing materials. The awards and honors he has received include 2015 Guest Professorship at ETH Zürich, 2014 Tang Ao-Qing Guest Professorship at Jilin University, 2013 Provost’s Faculty Achievement Award, 2013 Alfred P. Sloan Research Fellow, 2013 CAPA Distinguished Junior Faculty Award, 2012 3M Non-Tenured Faculty Award, 2011 National Science Foundation CAREER Award, and 2011 University New Inventor of the Year.

报告摘要：

Covalent organic frameworks (COFs) have emerged as a new class of porous materials that exhibit light weight, intrinsic porosity, high physiochemical stability, ordered structures, and structural tunability. Their chemical compositions are usually well-defined and inter-monomer connectivity (covalent bonding) is very robust. Moreover, various functional groups can be introduced in a controlled fashion through rational design of the precursors. This talk will focus on our recent progress in the target-driven design and synthesis of functional COF materials, and their applications in ion transportation, controlled nanoparticle growth and catalysis will also be discussed.
