The foci of this research are threefold. First, substructures of "phenylogous cubic graphite" will be synthesized to afford crystalline materials that are thermally stable porous solids. Second, hydrogen-bonding and salt-bridge-forming functional groups will be incorporated into polyphenyl aromatic molecules to serve as precursors to porous, three-dimensional network solids. Third, configurationally stable, chiral twisted polyphenyl aromatics will be synthesized. Crystals of the pure enantiomers of these molecules will contain chiral cavities, a property very rare in existing porous materials. With this award, the Organic and Macromolecular Chemistry Program is supporting the research of Dr. Robert A. Pascal of the Department of Chemistry at Princeton University. Dr. Pascal will focus his work on developing methodology for the synthesis and characterization of large polyphenyl aromatic compounds. These molecules have well-defined conformations, large cavities and great stability. It is projected that some of them will form highly stable, ordered, porous solids-essentially "hydrophobic zeolites." In terms of broader impacts, the project has potential for catalysis, separation technologies, and perhaps medical diagnostics. The project also provides an excellent setting for the training of graduate and undergraduate students.

这项研究的焦点是三倍。 首先，将合成“苯基立方石墨”的子结构，以提供热稳定的多孔固体的结晶材料。 其次，将将氢键和盐桥形成官能团纳入聚苯基芳族分子中，以作为多孔三维网络固体的前体。 第三，将合成构型稳定的手性扭曲的多苯基芳香族。 这些分子的纯对映异构体的晶体将包含手性腔，这是现有多孔材料非常罕见的特性。有了这个奖项，有机和大分子化学计划正在支持普林斯顿大学化学系的罗伯特·帕斯卡尔博士的研究。 Pascal博士将重点放在开发大型聚苯基芳族化合物的合成和表征的方法上。 这些分子具有明确的构象，较大的空腔和良好的稳定性。 预计其中一些将形成高度稳定的，有序的，多孔的固体“疏水性沸石”。 在更广泛的影响方面，该项目具有催化，分离技术以及医学诊断的潜力。 该项目还为培训研究生和本科生提供了绝佳的环境。
