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）资助的。本项目重点发展可控钯催化的交叉偶联聚合。其目的是：(a)发展Pd(0)催化的铃木交叉偶联聚合，聚合度可控；(b)发展其他Pd(0)催化的可控交叉偶联聚合，用于制备共轭聚合物及其相关共轭大分子。这些目标将通过缩小共轭聚合物的多分散指数来实现。还将进行在每个嵌段/段的聚合程度可控的共轭嵌段共聚物、刷状聚合物和星爆聚合物的制备研究。通过这个奖项，有机和大分子化学项目支持了纽约市立大学史泰登岛学院化学系胡乔生教授的研究。胡教授的研究工作围绕着交叉偶联聚合方法的发展，以合成共轭聚合物。所提出的研究有望揭示钯催化的新机会，并允许获得各种聚合程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.
