This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This project seeks to develop a novel living and stereoselective anionic polymerization using novel dinuclear ambiphilic silicon catalysts. Building off the recently developed anionic polymerization catalyzed by silylium ions, this project will continue work on the development of new features that will enable this new polymerization system to become an important and versatile technique serving for a wide range of living polymerization reactions and precision polymer synthesis. Such new features include covalently linked dinuclear ambiphilic silicon catalysts for fast propagating rates, asymmetric silicon catalysts for stereoregular polymer synthesis, and efficient processes for converting biorenewable monomers to sustainable polymers. With this award, the Organic and Macromolecular Chemistry Program is supporting the research of Professor Eugene Chen of the Department of Chemistry at Colorado State University. Professor Chen's research efforts revolve around the development of new organosilicon chemistry and polymerization catalysis by highly reactive silylium ions. Such chemistry and catalysis will contribute to the discovery and understanding in organic and organometallic chemistry, polymer synthesis, and sustainable chemistry. This research is important in chemical catalysis and polymer synthesis, areas central to the global economy.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。该项目旨在使用新型双核双亲硅催化剂开发新型活性和立体选择性阴离子聚合。 在最近开发的硅鎓离子催化的阴离子聚合的基础上，该项目将继续开发新的功能，使这种新的聚合系统成为一种重要的多功能技术，用于广泛的活性聚合反应和精密聚合物合成。 这些新的功能包括共价连接的双核双亲硅催化剂的快速增长率，不对称硅催化剂的有规立构聚合物合成，和有效的方法转化为可持续的聚合物生物可再生单体。有了这个奖项，有机和高分子化学计划正在支持科罗拉多州立大学化学系的尤金Chen教授的研究。 陈教授的研究工作围绕新型有机硅化学的开发和高反应性硅离子的聚合催化。 这些化学和催化将有助于发现和理解有机和有机金属化学，聚合物合成和可持续化学。 这项研究在化学催化和聚合物合成中非常重要，这些领域对全球经济至关重要。
