Unusual Structure in Polyphenyl Aromatic Molecules

本研究的重点是制备和表征各种直线型多苯基芳烃和大量的大环和支链多苯基芳烃。合成前一类化合物的关键步骤是聚苯芳烃和二烯的Diels-Alder反应。后一种化合物的合成将在很大程度上取决于芳烃和多苯基芳烃与一系列多苯基环戊二烯酮的反应。该化合物具有易于合成、易于衍生化、构象明确、稳定性好、溶解性好等特点，具有很好的研究和应用价值。将探讨其在电化学、光化学和主客体目的中的应用。有了这个更新奖，合成有机项目支持了普林斯顿大学化学系的罗伯特·a·帕斯卡博士的研究。帕斯卡尔教授将把他的工作重点放在制备和表征非常大的多苯基芳香族化合物。这些化合物在电化学、光化学和主客体化学等方面具有重要的应用价值。

The foci of this research are the preparation and characterization of a variety of linear perphenyl acenes and numerous macrocyclic and branched polyphenyl aromatics. The key steps in the syntheses of the former class are Diels-Alder reactions of polyphenyl arynes and dienes. Syntheses of the latter compounds will depend heavily on the reactions of aromatic alkynes and polyphenyl arynes with an array of polyphenylcyclopentadienones. The ease of synthesis, ease of derivatization, well-defined conformation, great stability and excellent solubility properties make the compounds excellent candidates for study and application. Applications for use in electrochemical, photochemical and host-guest purposes will be probed. With this renewal award, the Synthetic Organic Program is supporting the research of Dr. Robert A. Pascal of the Department of Chemistry at Princeton University. Professor Pascal will focus his work on the preparation and characterization of very large polyphenyl aromatic compounds. These compounds have potential for having great value in electrochemical, photochemical and host-guest applications.
