摘要： 

   Metallopolymers combine synthetic efficiency and versatility of an organic polymer framework with unique properties of inorganic metals. Advances in polymerization techniques have provided opportunities to prepare polymers with tunable chemistry and compositions, controlled topologies, predetermined molecular weight and narrow molecular weight distribution. In this presentation, I will talk about the latest development from chemoselective synthesis of cationic metallocene derivatives to the use of controlled and living polymerization for the preparation of well-defined polyelectrolytes. These cationic polyelectrolytes have shown surprising promise as novel antimicrobial agents that could kill some of most malicious bacteria. I will discuss a new strategy to addressing bacteria resistance via revitalizing conventional β-lactam antibiotics. I will also introduce a new class of metallopolymer hydrogels that can recycle antibiotics from waste water. The multifunctional characteristics of these hydrogels highlight the potential for metallopolymers in the field of healthcare and environmental treatment.
