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。该项目旨在开发一种使用新型双核亲硅催化剂的新型活性和立体选择性阴离子聚合。在最近开发的硅离子催化阴离子聚合的基础上，该项目将继续开发新功能，使这一新的聚合系统成为一项重要的通用技术，为广泛的活性聚合反应和精密聚合物合成服务。这些新功能包括用于快速繁殖的共价连接双核亲硅催化剂，用于立体规则聚合物合成的不对称硅催化剂，以及将生物可再生单体转化为可持续聚合物的高效工艺。通过这一奖项，有机和高分子化学项目支持科罗拉多州立大学化学系的尤金·陈教授的研究。陈教授致力于开发新的有机硅化学和高活性硅离子聚合催化。这样的化学和催化作用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领域非常重要，这两个领域对全球经济至关重要。

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.
