Chemoselective Synthesis and Advanced Applications of Metallo-Polyelectrolytes
报告摘要：Charged metal-containingv polymers or metallo-polyelectrolytes are a new class of polyelectrolytes. The presenceof metal cations empowers them with unique electronic, ionic binding and redox properties that traditional organo-polyelectrolytes do not possess. Cationic metallocene is a bulky cation with metal embedded within asandwich-type structure. In this presentation, I will talk about the latest efforts on chemoselective synthesis of cationiccobaltocenium and rhodocenium derivatives as well as controlled polymerization toward multifunctional polyelectrolyteswith a variety of macromolecular topologies and compositions. On the other hand, these novel polyelectrolytes havefound many utilities that play an active role in promoting sustainability in health and energy. I will discuss the use ofthese metallo-polyelectrolytes as antimicrobial biomaterials for killing multidrug-resistant bacteria and as anion-exchangemembranes for ion transport in alkaline fuel cells. I will elucidate the effects of macromolecular compositionsand topologies on functions of each application. 报告人简介：Dr. Chuanbing Tang received B.S. from Nanjing University, M.S. and Ph.D. from Carnegie Mellon University,and worked as a postdoctoral scholar at the University of California Santa Barbara.
