报告内容：
Cobalt-catalyzed carbonylative polymerization (COP) of heterocycles is potentially a useful method for synthesis of a wide range of polyamides and polyesters. The presentation will first focus on the development of this class of catalytic polymerization. The evolving mechanistic understanding will be discussed based on our synthetic explorations and kinetic studies. The scope and limitation of the polymerization will be then discussed, including the suitable monomer types for the polymerization and the control of the microstructure and architecture of the polymer products.
The properties of the poly(b-alanoid)s (X = NR) synthesized via COP of aziridines will be then presented. The superb protein-adsorption resistance of the highly water-soluble members of poly(b-alanoid)s (R = Me or Et) is demonstrated by surface plasma resonance spectroscopy.
Finally, oligo(b-alanine)s as a new physical crosslinking platform for thermoplastic elastomers will be presented. Only a few weight percent of oligo(b-alanine)s is necessary for physical crosslinking to occur. The oligo(b-alanine)s form filaments in the elastomeric matrix according to transmission electron microscopy.
Li Jia教授简介：
Dr. Jia Li was graduated from Lanzhou University (BS, 1991), and Northwestern University (1996, Ph.D). He went to University of California (Lawrence Berkeley Laboratory) as a postdoctoral fellow (1996-1998). He joined Lehigh University as an assistant professor (1998-2005), and then went to Rohm and Haas Electronic Materials as Senior Scientist and Group Leader (2005-2007). He joined Department of Polymer Science of The University of Akron as an assistant professor (2007-2011) and promoted to associate professor (2011- ). His research interests include metal-catalyzed polymerizations, photoresist polymers and materials, colloidal self-assembly and soft lithography, and supramolecular self-assembly.
