CAREER: Boron-Containing Polymeric Lewis Acids in Supramolecular Chemistry and Materials Science

罗格斯大学纽瓦克分校化学系的Frieder Jaekle教授得到了有机和高分子化学项目的支持，他的研究重点是制备和探索新的无机聚合物，用于材料化学领域。具有受控分子量和明确聚合物结构的硼基聚合刘易斯酸将通过包括三个步骤的模块化方法制备：（1）控制合成各种结构的官能化聚合物，包括均聚物、无规共聚物、嵌段共聚物和遥爪聚合物，（2）用卤化硼或其它强刘易斯酸定量取代官能团，和（3）通过高产率取代反应微调各个位点的刘易斯酸性，以获得一族新的聚合刘易斯酸。他将利用刘易斯酸和刘易斯碱之间供体-受体键的自发和可逆形成，开发用于合成嵌段共聚物和接枝聚合物以及聚合物可逆交联的创新方法。此外，Jaekle教授将利用高稳定性阴离子硼酸盐和阳离子硼中心的形成来开发新的无机聚电解质和两亲性嵌段共聚物。在有机与高分子化学项目的支持下，将开发一门“材料化学”本科实验课程，其中包括烯烃活性聚合、共轭聚合物的表征、聚合物纳米结构的表征、聚合物纳米结构的（电活性）聚合物和纳米颗粒的形成。这一努力将加强聚合物和材料化学领域高度多样化的学生群体的培训。还将与当地高中建立一个新的聚合物化学推广方案，以吸引少数民族学生进入科学领域。

Professor Frieder Jaekle of the Department of Chemistry at Rutgers University- Newark is supported by the Organic and Macromolecular Chemistry Program to perform research that focuses on the preparation and exploration of new inorganic polymers for applications in the field of materials chemistry. Boron-based polymeric Lewis acids of controlled molecular weight and well-defined polymer architecture will be prepared through a modular approach that involves three steps: (1) the controlled synthesis of functionalized polymers of various architectures including homopolymers, random copolymers, block copolymers, and telechelic polymers, (2) the quantitative replacement of the functional groups with boron halides or other strong Lewis acids, and (3) the fine-tuning of the Lewis acidity of the individual sites through high-yield substitution reactions to give access to a family of new polymeric Lewis acids. He will take advantage of the spontaneous and reversible formation of donor-acceptor bonds between Lewis acids and Lewis bases for the development of innovative methods for the synthesis of block copolymers and graft polymers as well as the reversible cross-linking of polymers. Furthermore, Professor Jaekle will use the formation of highly stable anionic borate and cationic boronium centers for the development of new inorganic polyelectrolytes and amphiphilic block copolymers. The described research efforts are likely to result in discoveries of novel thermo-reversible polymers, of polymeric nanostructures, and of new functional materials.With the support of the Organic and Macromolecular Chemistry Program, a "Materials Chemistry" Undergraduate Laboratory Course will be developed that includes research level experiments on the living polymerization of olefins, the characterization of conjugated (electro-active) polymers, and the formation of nanoparticles. This effort will enhance the training of a highly diverse student population in the areas of polymer and materials chemistry. A new polymer chemistry Outreach Program with local high schools will also be established in an effort at attracting minority students into the sciences.
