Dehydrogenative Coordination Polymerizations to New Polymeric Materials

该奖项由材料合成和加工倡议下的化学部门和材料研究部门的特殊项目办公室颁发。研究了硅烷的脱氢缩聚反应。研究将集中在学习如何控制聚合物在金属中心的生长，开发新的催化剂，以及应用新的化学方法来生产具有全新性能的功能化聚合物。将制备在聚合物主链中含有烃类不饱和或过渡金属中心的杂化硅聚合物。脱氢偶联将扩展到其他金属，如锡烷，以产生含有锡-锡键的新聚合物。含有氧化还原活性金属中心的聚合物将为新型导电聚合物、磁性活性聚合物、大分子催化剂或电极介质系统提供途径。

This award is made in the Office of Special Projects of the Chemistry Division and the Division of Materials Research under the Materials Synthesis and Processing Initiative. Dehydrogenative condensation polymerization of silanes will be studied. The research will focus on learning how to control polymer growth at the metal center, development of new catalysts, and application of the new chemistry to produce functionalized polymers with radically new properties. Hybrid silicon polymers that contain hydrocarbon unsaturation or transition metal centers in the polymer backbone will be made. Dehydrogenative coupling will be extended to other metals such as stannanes to produce new polymers containing tin-tin bonds. %%% Polymers containing redox-active metal centers will provide access to new conducting polymers, magnetically active polymers, macromolecular catalysts or electrode mediator systems.
