number of [n]phenacenes in the hope that they might be useful as the bridging groups for electron transfer processes in donor–bridge–acceptor molecules. Because [n]phenacenes with n > 5 are very insoluble, their synthesis and characterization has required the attachment of solubilizing substituents such as tert-butyl. The studies of Pascal and co-workers of some large polynuclear aromatic compounds
近年来,我们已使用二芳基乙烯的光环化反应来合成许多[ n ]苯并菲,希望它们可用作供体-桥-受体分子中电子转移过程的桥基。因为n > 5的[ n ]苯并菲是非常不溶的,所以它们的合成和表征需要连接可溶取代基,例如叔丁基。对具有多个苯基取代基的一些大型多核芳族化合物的Pascal及其同事的研究促使我们探索使用苯基作为[ n ]苯并菲的替代增溶基团。尽管事实证明,与提供的苯基相比,苯基的溶解度要低得多在这些化合物中的叔丁基上,我们发现了苯基取代的和叔丁基取代的[ n ]苯并菲的一些有趣的结构比较。
