With this renewal proposal the Organic and Macromolecular Chemistry Program continues its support for the work of Professor Richard G. Weiss of the Department of Chemistry at Georgetown University in Washington, DC. The research will extend the PI's work on novel materials and their ability to mediate the reactivity of guest molecules. The materials will consist of self-assembling systems such as ionic liquid crystals, thermally or chemically reversible organogels, and sets of related polymers that can be varied structurally and morphologically. An important goal of this research is to understand static and dynamic interactions that occur when molecules meet molecules in anisotropic environments. The way in which energy is deposited into materials will also be explored by examining the consequences of UV-Vis and ionizing radiation on the guest molecules and their hosts.The proposed studies are expected to assist the development of green solvents, media for 3-dimensional structure elucidation, and membranes for molecular separations. An important component of this research will involve the training of young scientists, including those in under-represented groups and from developing countries.

有了这个更新的建议，有机和高分子化学计划继续支持教授理查德G。华盛顿乔治敦大学化学系的韦斯说。 这项研究将扩展PI在新材料及其介导客体分子反应性的能力方面的工作。 这些材料将由自组装系统组成，如离子液晶，热或化学可逆的有机凝胶，以及可以在结构和形态上变化的相关聚合物组。 这项研究的一个重要目标是了解分子在各向异性环境中遇到分子时发生的静态和动态相互作用。通过研究紫外-可见光和电离辐射对客体分子及其主体的影响，探索能量沉积到材料中的方式，预计这些研究将有助于绿色溶剂、三维结构解析介质和分子分离膜的开发。 这项研究的一个重要组成部分将涉及培训青年科学家，包括代表人数不足的群体和来自发展中国家的青年科学家。
