项目摘要

The Macromolecular, Supramolecular, and Nanochemistry Program supports Professor David A. Vanden Bout of the University of Texas at Austin to develop strategies to study the fundamental nature of energy transport in supramolecular and macromolecular organic systems such as tubular molecular aggregates, single conjugated polymers, and polymer aggregates. The research program investigates the properties of these materials for energy transport applications by combining a number of super-resolution imaging techniques. A goal is to directly probe energy transport in individual nanoscale systems, coupling both temperature and electric field dependence measurements to examine how disorder and electronic coupling affect energy migration. By studying both polymer systems as well as self-assembled supramolecular systems, the results will help to separate the effects of intra- and intermolecular interactions in energy transfer events.By studying how energy can be collected and moved in organic materials, this research will help to formulate new materials for light harvesting and solar energy. The research will use methods that directly probe the migration of energy in individual systems to overcome the inherent complexities of the bulk materials. The research project will also seek to increase the number and diversity of students pursuing chemical research via the inclusion of undergraduate students in the research program.

大分子，超分子和纳米化学计划支持教授大卫A。德克萨斯大学奥斯汀分校的Vanden Bout制定策略来研究超分子和大分子有机系统（例如管状分子聚集体、单一共轭聚合物和聚合物聚集体）中能量传输的基本性质。该研究计划通过结合一些超分辨率成像技术来研究这些材料在能量传输应用中的特性。一个目标是直接探测单个纳米级系统中的能量传输，耦合温度和电场依赖性测量，以研究无序和电子耦合如何影响能量迁移。通过研究聚合物体系和自组装超分子体系，研究结果将有助于分离能量传递事件中分子内和分子间相互作用的影响。通过研究能量如何在有机材料中收集和移动，这项研究将有助于制定用于光捕获和太阳能的新材料。该研究将使用直接探测单个系统中能量迁移的方法，以克服散装材料固有的复杂性。该研究项目还将寻求通过将本科生纳入研究计划来增加从事化学研究的学生的数量和多样性。
