With this renewal award the Organic and Macromolecular Chemistry Program supports the continuing research of Dr. Nicholas J. Turro of the Department of Chemistry at Columbia University. The proposed research involves collaborative investigations of the structures and dynamics of a variety of supramolecular systems in which reactive intermediates are generated by uv photolysis. Included are geminate radical pairs and biradicals generated in micelles, radicals, radical pairs, and biradicals generated on the external and internal surfaces of zeolites, and supramolecular assemblies resulting from the interactions of DNA with dendrimers. Enantiomeric selection in spin chemistry will be explored, including possible connections between angular momentum, optical activity, and molecular chirality.Fundamental investigations are proposed to characterize novel materials with unusual properties, and to elucidate mechanisms of binding of small guest molecules to biomolecules. The work is interdisciplinary and has potential applications in catalysis, size and shape selective separations, and materials science. It will integrate research and education by actively involving undergraduate and graduate students at Columbia in research projects coupled to instruction through the use of the world wide web and other information technologies.

有了这个更新奖的有机和高分子化学计划支持化学系在哥伦比亚大学的Nicholas J. Turro博士的继续研究。 该研究计划包括对各种超分子体系的结构和动力学的合作研究，在这些体系中，活性中间体是通过紫外光分解产生的。 包括在胶束中产生的成对自由基和双自由基，在沸石的外表面和内表面上产生的自由基、自由基对和双自由基，以及由DNA与树枝状聚合物的相互作用产生的超分子组装体。 本课程将探讨自旋化学中对映体的选择，包括角动量、旋光活性和分子手性之间的可能联系，并提出基础研究以表征具有不寻常性质的新材料，以及阐明小客体分子与生物分子结合的机制。 这项工作是跨学科的，在催化，尺寸和形状选择性分离和材料科学中具有潜在的应用。 它将通过积极地使哥伦比亚大学的本科生和研究生参与研究项目，并通过使用万维网和其他信息技术，将研究和教育结合起来。
