A phenylene multiring with a corannulenoidal skeleton was synthesized. Geodesic constraints over 20 phenylene panels resulted in its nanometer-sized, bowl-shaped molecular structure, which was unequivocally revealed by crystallographic analysis. The crystal structure also showed the presence of a bowl-in-bowl dimeric assembly, which was driven by entropic factors in solution.
合成了具有 corannulenoidal 骨架的苯并多环。超过 20 个苯环的测地线约束导致其具有纳米级的碗状分子结构,这一点通过晶体学分析得到了明确的揭示。晶体结构还显示了存在碗中碗二聚体组装,这是由溶液中的熵因素驱动的。
