Super-resolution imaging of energy transport in supramolecular and macromolecular materials

大分子、超分子和纳米化学项目支持德克萨斯大学奥斯汀分校的David A.Vanden Bout教授开发策略，研究管状分子聚集体、单共轭聚合物和聚合物聚集体等超分子和大分子有机系统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系统中的能量传输，耦合温度和电场依赖的测量，以研究无序和电子耦合如何影响能量迁移。通过对聚合物体系和自组装超分子体系的研究，结果将有助于分离分子内和分子间相互作用对能量转移的影响；通过研究有机材料中能量的收集和转移，本研究将有助于开发新的聚光和太阳能材料。这项研究将使用直接探测单个系统中能量迁移的方法，以克服大宗材料固有的复杂性。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。

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.
