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.

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。 该项目的重点是受控钯催化交叉偶联聚合的开发。 其目的是：（a）开发具有受控聚合度的Pd（0）-催化的Suzuki交叉偶联聚合，和（B）开发用于制备共轭聚合物及其相关共轭大分子的其它受控Pd（0）-催化的交叉偶联聚合。 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/链段中具有受控聚合度的共轭嵌段共聚物、刷状聚合物和星状聚合物的制备的研究。 有了这个奖项，有机和高分子化学计划正在支持化学系教授Qiao-Sheng胡教授的研究在纽约市立大学史泰登岛学院。 胡教授的研究工作围绕着交叉偶联聚合方法的发展，用于合成共轭聚合物。 拟议的研究预计将揭示钯催化的新机会，并允许获得各种具有受控聚合度的共轭大分子。 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。
