Development of Controlled Palladium(0)-Catalyzed Cross-Coupling Polymerizations

该奖项是根据2009年《美国复苏和再投资法案》(公法111-5)提供资金的。本项目致力于发展受控钯催化的交叉偶联聚合。它的目标是：(A)开发可控聚合度的Pd(0)催化的Suzuki交叉偶联聚合，以及(B)开发其他可控的Pd(0)催化的交叉偶联聚合，以制备共轭聚合物及其相关的共轭大分子。这些目标将通过缩小共轭聚合物的多分散指数来实现。还将研究在每个嵌段/链段中控制聚合度的共轭嵌段共聚物、刷状聚合物和星爆聚合物的制备。通过这一奖项，有机化学和高分子化学项目将支持斯坦顿岛城市大学化学系胡乔生教授的研究。胡教授致力于开发用于合成共轭聚合物的交叉偶联聚合方法。这项拟议的研究有望揭示钯催化的新机会，并允许获得各种聚合度可控的共轭大分子。该方法的成功开发将对材料科学和纳米技术领域产生积极影响。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). This project focuses on the development of controlled palladium-catalyzed cross-coupling polymerizations. It aims: (a) to develop Pd (0)-catalyzed Suzuki cross-coupling polymerizations with a controlled degree of polymerization, and (b) to develop other controlled Pd (0)-catalyzed cross-coupling polymerizations for the preparation of conjugated polymers and their related conjugated macromolecules. These aims will be accomplished by narrowing the poly-dispersity index of the conjugated polymers. The studies on the preparation of conjugated block copolymers, brush polymers and starburst polymers with a controlled degree of polymerization in each block/segment will be also performed. With this award, the Organic and Macromolecular Chemistry Program is supporting the research of Professor Qiao-Sheng Hu of the Department of Chemistry at CUNY College of Staten Island. Professor Hu's research efforts revolve around the development of cross-coupling polymerization methods for the synthesis of conjugated polymers. The proposed research is expected to reveal new opportunities for palladium catalysis and to allow access to a variety of conjugated macromolecules with a controlled degree of polymerization. Successful development of the methodology will have a positive impact on the fields of materials science and nanotechnology.
