Molecular Approaches to the Design, Utilization, and Transformation of Assemblies

有机和大分子化学项目支持Richard Weiss教授关于液晶、聚合物和凝胶对客体分子的结构和/或电子各向异性影响的研究。将在流体溶液中具有确定的光谱和光化学性质的分子纳入这些介质中，并比较它们在不同介质中的反应性，以阐明介质施加的结构和电子影响。相反，明确的各向异性环境将被用来对客体施加特定的影响，从而提供对这些狭窄环境中影响特定转换的基本因素的见解。参与本研究的本科生和研究生将接触到各种光化学，快速反应和光谱技术，以及它们在材料表征中的应用。有了这个更新奖，有机和大分子化学项目支持乔治城大学Richard Weiss教授的研究和教育活动。Weiss教授的研究重点是阐明液晶、聚合物和凝胶对被称为客体的结合分子的光化学反应性所施加的结构和电子效应。这些材料施加的局部微环境会影响客体的反应性，而客体反应性的变化，与流体溶液中的反应性相比，为材料在分子水平上的加工提供了独特的见解。Weiss教授的教学活动包括对研究生和本科生进行光谱学、快速反应技术和材料表征方面的培训。

The Organic and Macromolecular Chemistry Program supports the studies of Professor Richard Weiss on the effects of structural and/or electronic anisotropy imposed by liquid crystals, polymers, and gels on guest molecules. Molecules with well-established spectral and photochemical properties in fluid solution will be incorporated into these media, and their reactivity in the different media compared to elucidate structural and electronic influences imposed by the media. Conversely, well defined anisotropic environments will be employed to impose specific influences on the guest thereby providing insights into the fundamental factors affecting specific transformations within these constrictive environments. Undergraduate and graduate students involved in this research will be exposed to a variety of photochemical, fast reaction and spectroscopic techniques, and their application to materials characterization. With this Renewal award, the Organic and Macromolecular Chemistry Program supports the research and educational activities of Professor Richard Weiss of Georgetown University. Professor Weiss will focus his research on elucidating the structural and electronic effects imposed by liquid crystals, polymers, and gels on the photochemical reactivity of incorporated molecules, called guests. The local microenvironment imposed by these materials influences the reactivity of the guest, and changes in the reactivity of the guest, when compared to that in fluid solution, offer unique insights into materials processing at the molecular level. The educational activities of Professor Weiss include the training of graduate and undergraduate students in spectroscopy, fast reaction techniques and materials characterization.
