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.

在该项目中，由化学系高分子、超分子和纳米化学项目资助，弗吉尼亚理工大学和州立大学的路易斯·马德森将研究一系列高度有序的离子传导材料中离子输运、形态和化学结构之间的相互作用。 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堆积分子形成。 它们将自组装成超分子柱，其中磺酸基团堆叠形成明确的离子通道。 Madsen 将使用先进的多模态 NMR 方法来探测这些材料，并将成为国际合作的一部分，其中 Martin Moller（德国亚琛）将进行高度定制的合成，而 Dimitri Ivanov（法国国家科学研究中心，法国米卢斯）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。 这个星球上的可持续生命需要开发清洁水和可再生能源。 下一代能源和环境相关技术将依赖先进材料的开发，使其超越单纯的理论。 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世界研究和教育基础设施的建设，并在此过程中教育美国学生和研究人员参与全球科学事业。
