Abstract: Polyelectrolytes are a class of macromolecules containing charged groups. The fields of macromolecular sciences have enjoyed a unique combination of metals and soft organic frameworks in the name of metallopolymers, metal-containing polymers or organometallic polymers. When metallopolymers carry charged groups, they form a class of polyelectrolytes or metallo-polyelectrolytes. This is an emerging area that is particularly well suited for manufacturing functional materials. This presentation will focus on a few unique properties and functions of metallo-polyelectrolytes that conventional organo-polyelectrolytes, do not possess. Particularly I will talk about cationic metallocene-containing polyelectrolytes on the following perspectives: (1) electronic, bonding, and redox properties; (2) directed self-assembly; (3) functional materials via electrostatic interactions; (4) ion-exchange for transport. A perspective on the critical challenges will be discussed, especially on experimental quantitative analysis and theoretical modelling of ionic binding.
Biography: Dr. Chuanbing Tang received B.S. from Nanjing University, and Ph.D. from Carnegie Mellon University with Profs. Krzysztof Matyjaszewski and Tomasz Kowalewski. He was a postdoctoral scholar at the University of California Santa Barbara with Profs. Craig J. Hawker and Edward J. Kramer. He joined the University of South Carolina in 2009. Currently he is a Distinguished Professor at the College of Arts and Sciences, Department of Chemistry and Biochemistry. His research is generally themed on organic polymer chemistry interfaced with medicinal chemistry and advanced materials, with topics including on sustainable biobased polymers from renewable biomass, synthetic organometallics and metallopolymers, functional polymers for biomedical and energy applications. He has been recognized with many awards and honor, including Fellow of Polymer Chemistry Division of American Chemical Society, ACS Local Section Outreach Volunteer of the Year Award, Kavli Fellow of National Academy of Sciences, Fellow of Royal Society of Chemistry, Presidential Early Career Award for Scientists and Engineers, South Carolina Governor's Young Scientist Award for Excellence in Scientific Research, NSF Career Award, and USC Distinguished Undergraduate Research Mentor Award. He is now an editor of Polymer and a former associate editor of Polymer Reviews, and serves on a few editorial advisory boards of major polymer journals including Macromolecules, ACS Macro Letters, Macromolecular Rapid Communications, Macromolecular Chemistry and Physics. He has edited one book, published over 120 papers and 15 patents.
