Conformationally Exceptional Arenes and Polyarylenes

本项目主要研究两类芳香大分子。第一类涉及新的聚苯、大环、聚丙烯纳米结构。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，具有形成热稳定多孔固体的潜力。第二类是构型稳定的手性扭曲芳香分子。这些分子的对映体预计会表现出很高的旋光度和强圆偏振发光。这些分子的纯对映体晶体中会含有手性空腔，这在现有材料中是罕见的。通过这个奖项，有机和大分子化学项目支持了普林斯顿大学化学系Robert A. Pascal教授的研究。帕斯卡尔教授和他的学生将研究两类大型的、不寻常的芳香化合物。这些新型芳香族化合物及其多孔晶体在催化、分离技术和医学诊断等方面具有广泛的应用前景。它们也是显示技术中使用的有机电子材料的候选材料

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
