The Development of Metallo-Supramolecular Materials

本项目致力于利用金属超分子聚合物独特的化学性质来开发新型材料。具体地说，金属超分子聚合物作为复杂结构、嵌段共聚物和催化剂模板的潜力将被研究。目标复杂的体系结构包括聚[n]链烷。该合成方案以金属-配体配位为聚合的热力学驱动力，以动态合环复分解为共价固定步骤。对于嵌段共聚物，将研究利用金属-配体配位自组装嵌段共聚物结构的能力。对于催化剂，潜在的刺激响应性催化将被研究。通过这一奖项，有机化学和高分子化学项目支持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使用金属超分子聚合物的新型材料的发现和开发展开。这些材料在分子致动器、交织聚合物和高度热稳定性器件等领域具有广阔的应用前景。它们还有望制造出对外部刺激做出反应的智能催化剂。这种智能催化剂在医药和电子材料的制造中可能有重要的应用。

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.
