The Phenylenes

伯克利这项研究的重点是用过渡金属组装高能的炔前体，然后齐聚生成具有线形、角形、C3对称、环状、弯曲和锯齿状拓扑结构的苯系物。在结构上有意义的发现包括苯环“无芳香性”和观察到的强曲率。通过这种方法，有可能获得球状和平面碳氢化合物以及碳网和石墨化‘洋葱’等材料。有了这一续期奖，合成有机计划将支持加州大学伯克利分校化学系K·彼得·C·沃尔哈特博士的研究。沃尔哈特教授将专注于制备一类被称为苯类的新型苯型碳氢化合物。这些苯类化合物含有稠合的环丁二烯与苯环交替的结构，提供了具有作为有机分子磁性和/或导电材料的潜力的体系，并作为大量其他具有新拓扑结构的新型高能化合物的前体。

Berkeley The focus of this research is the preparation of phenylenes employing methodology in which transition metals are used to assemble highly energetic alkyne precursors which are then oligomerized to produce phenylenes with linear, angular, C3-symmetric, circular, bent and zigzag topologies. Structurally significant discoveries have included benzene rings `devoid of aromaticity` and the observation of strong curvature. Access to spherical and planar hydrocarbons as well as materials such as carbon nets and graphitic `onions` is potentially available through this approach. With this renewal award, the Synthetic Organic Program is supporting the research of Dr. K. Peter C. Vollhardt of the Department of Chemistry at the University of California, Berkeley. Professor Vollhardt will focus his work on preparing a class of novel benzenoid hydrocarbons known as phenylenes. The phenylenes contain structures in which fused cyclobutadienes alternate with benzene rings to afford systems that have potential as organic molecular magnetic and/or conducting materials, and serve as precursors to a plethora of other novel classes of highly energetic compounds with novel topologies.
