The anellation of a 6-membered ring to the 2,3-position of corannulene (=dibenzo[ghi,mno]fluoranthene; 1) leads to curved aromatic compounds with a significantly higher bowl-inversion barrier than corannulene (see Fig. 1). If the bridge is −CH2−NR−CH2−, a variety of linkers can be introduced at the N(2) atom, and the corresponding curved aromatics act as versatile building blocks for larger structures
将 6 元环与 corannulene (=dibenzo[ghi,mno]fluoranthene; 1) 的 2,3-位的环化导致弯曲的芳族化合物具有比 corannulene 显着更高的碗反转势垒(见图 1) . 如果桥是-CH2-NR-CH2-,则可以在 N(2) 原子处引入各种连接体,并且相应的弯曲芳烃可作为更大结构的通用构件(参见方案)。锁定碗与酰胺键(见 9 和 10)结合,产生具有手性基态构象的 corannulene 衍生物,它们具有通过稍微改变对映异构体平衡以有利于一种对映异构体来适应其手性环境的能力构象者。在 [5,
