The Development of Metallo-Supramolecular Materials

本项目的重点是利用金属超分子聚合物的独特化学性质来开发新型材料。具体来说，金属超分子聚合物作为复杂结构模板、嵌段共聚物和催化剂的潜力将被研究。所针对的复杂结构包括聚[n]链烷。该合成方案利用金属配位作为聚合的热力学驱动力，并利用动态合环复分解作为共价“固定”步骤。对于嵌段共聚物，将研究利用金属配位自组装嵌段共聚物结构的能力。对于催化剂，潜在的刺激反应催化将被研究。有了这个奖项，有机和大分子化学项目支持了凯斯西储大学化学系的斯图尔特·j·罗文教授的研究。罗文教授的研究工作围绕着使用金属超分子聚合物的新材料的发现和发展。这些材料在分子致动器、交织聚合物和高度热稳定器件领域具有前景。它们还有望成为对外部刺激作出反应的智能催化剂。这种智能催化剂在制药和电子材料的制造中有重要的应用。

This project is focused on exploiting the unique chemical properties of metallo-supramolecular polymers to develop novel materials. Specifically, the potential of metallo-supramolecular polymers as templates for complex architectures, block copolymers, and catalysts will be studied. The complex architectures targeted include poly[n]catenanes. The synthetic protocol utilizes metal-ligand coordination as the thermodynamic driving force for the polymerization and dynamic ring closing metathesis as the covalent 'fixing' step. For block copolymers, the ability to self-assemble block copolymer architectures using metal-ligand coordination will be studied. For catalysts, potentially stimuli-responsive catalysis will be investigated. With this award, the Organic and Macromolecular Chemistry Program is supporting the research of Professor Stuart J. Rowan, of the Department of Chemistry at Case Western Reserve University. Professor Rowan's research efforts revolve around the discovery and the development of novel materials using metallo-supramolecular polymers. These materials hold promise in the areas of molecular actuators, interwoven polymers, and highly thermo-stable devices. They also hold promise for smart catalysts that respond to external stimuli. This kind of smart catalysts could have important applications in the manufacturing of pharmaceuticals and electronic materials.
