Conformationally Exceptional Arenes and Polyarylenes

本课题主要研究两类大分子芳香族化合物。第一类涉及新的多苯基、大环、聚芳烃纳米结构。这些分子很大，有很高的表面积。它们具有很强的分子间相互作用，有可能形成热稳定的多孔性固体。第二类是构型稳定、手性、扭曲的芳香分子。这些分子的对映体有望表现出很高的旋光度和很强的圆偏振发光。这些分子的纯对映体的晶体将含有手性空腔，这在现有材料中是很少见的。通过这一奖项，有机化学和高分子化学项目支持普林斯顿大学化学系罗伯特·A·帕斯卡教授的研究。帕斯卡教授和他的学生将研究两类大的、不寻常的芳香化合物。这些新型芳香族化合物及其多孔性晶体可能在催化、分离技术和医学诊断方面有应用。它们也是用于显示技术的有机电子材料的候选者

This project is focused on the study of two classes of large aromatic molecules. The first class deals with new polyphenyl, macrocyclic, polyarylene nanostructures. These molecules are large and have high surface areas. They have strong intermolecular interactions and have the potential to form thermally stable porous solid. The second class is configurationally stable, chiral, twisted aromatic molecules. The enantiomers of these molecules are expected to show very high optical rotations and strong circularly polarized luminescence. The crystals of the pure enantiomers of these molecules will contain chiral cavity, which is rare in existing materials. With this award, the Organic and Macromolecular Chemistry Program is supporting the research of Professor Robert A. Pascal of the Department of Chemistry at Princeton University. Professor Pascal and his students will investigate two classes of large, unusual aromatic compounds. These novel aromatic compounds and their porous crystals may have application in catalysis, separation technologies, and medical diagnostics. They are also candidates for organic electronic materials used in display technologies
