Unusual Structure in Polyphenyl Aromatic Molecules

本研究的重点是各种直链全苯并苯和大量的大环和支化多苯芳烃的制备和表征。前一类化合物合成的关键步骤是多苯芳烃和二烯的Diels-Alder反应。后一类化合物的合成将在很大程度上依赖于芳香烃和多苯基芳烃与一系列聚苯基环戊二酮的反应。这些化合物具有易合成、易衍生化、构象清晰、稳定性好以及良好的溶解性能等优点，是研究和应用的极佳材料。将探索在电化学、光化学和主客体用途方面的应用。有了这一续期奖，合成有机计划将支持普林斯顿大学化学系罗伯特·A·帕斯卡博士的研究。帕斯卡教授将把工作重点放在非常大的多苯基芳香族化合物的制备和表征上。这些化合物在电化学、光化学和主客体等方面都有很大的应用价值。

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.
