In this project, funded by the Macromolecular, Supramolecular and Nanochemistry Program of the Chemistry Division, Louis Madsen of Virginia Polytechnic and State University will investigate interactions between ion transport, morphology, and chemical structure in a range of highly ordered ion-conducting materials. These materials will be formed using wedge-shaped amphiphilic pi-stacked molecules with focal hydrophilic sulfonic acid head groups. These will self-assemble into supramolecular columns, in which sulfonic groups stack to form well defined ion channels. Madsen will use advanced multi-modal NMR methods to probe these materials, and will be part of an international collaboration in which Martin Moller (U. Aachen, Germany) will conduct highly tailored synthesis, and Dimitri Ivanov (CNRS, Mulhouse, France) will accomplish advanced X-ray and microscopy analyses. The broader impacts include developing a world infrastructure for research and education via international collaborations. Graduate students and postdocs will benefit from tailored mentoring programs as well as the international dimension of this work. Developing clean water and renewable energy sources will be required for sustainable life on this planet. Next-generation energy and environment-related technologies will rely on development of advanced materials in order to bring them beyond mere theories. This project will provide new insights into conductive materials to meet these grand challenges. An international collaboration with outstanding researchers in France and Germany will foster a world infrastructure for research and education, and in the process will educate US students and researchers in the global scientific enterprise.

在这个项目中，由化学部的大分子，超分子和纳米化学计划资助，弗吉尼亚理工大学和州立大学的Louis Madsen将研究离子传输，形态和化学结构之间的相互作用，在一系列高度有序的离子传导材料中。 这些材料将使用具有焦点亲水性磺酸头基的楔形两亲性π堆叠分子形成。 这些将自组装成超分子柱，其中磺酸基堆叠形成明确的离子通道。 马德森将使用先进的多模态核磁共振方法来探测这些材料，并将成为一个国际合作的一部分，其中马丁穆勒（美国）。亚琛，德国）将进行高度定制的合成，和迪米特里伊万诺夫（CNRS，穆尔豪斯，法国）将完成先进的X射线和显微镜分析。 更广泛的影响包括通过国际合作开发世界研究和教育基础设施。 研究生和博士后将受益于量身定制的指导计划以及这项工作的国际层面。 开发清洁水和可再生能源将是地球上可持续生活的必要条件。 下一代能源和环境相关技术将依赖于先进材料的开发，以使其超越理论。 该项目将为导电材料提供新的见解，以应对这些重大挑战。 与法国和德国杰出研究人员的国际合作将促进研究和教育的世界基础设施，并在此过程中将教育美国学生和研究人员在全球科学企业。
