开发了一条合成功能化四氢[5]菲的合成路线，以此为前驱体，合成了含有四个碳-碳三键的脱氢苯并[32]轮烯大环。大环化步骤的高效率可以归因于其直接前体的结构刚性。四个碳-碳三键的氢化生成了一个大环，其碳骨架为[16]环吩烯，是(8，8)扶手椅碳纳米管中最短的大环带状结构。
A synthetic pathway to a functionalized tetrahydro[5]phenacene was developed, which served as a precursor, leading to a dehydrobenzo[32]annulene macrocycle containing four carbon–carbon triple bonds. The high efficiency of the macrocyclization step can be attributed to the structural rigidity of its immediate precursor. Hydrogenation of the four carbon–carbon triple bonds produced a macrocycle bearing a carbon framework of [16]cyclophenacene as the shortest macrocyclic belt-like structure of an (8,8)armchair carbon nanotube.
