Abstract
AbstractMost of the bowl‐shaped molecules are synthesized via a core‐periphery strategy with the bowl rim closed at the final stage. However, the construction of heteroatom‐doped buckybowls by the periphery‐core method with the bowl bottom sealed by inserting new atoms in the last step is quite limited. Herein we report the synthesis of a bowl‐shaped compound containing four sulfur atoms and two embedded N−B bonds with the ratio of carbon atom and heteroatom as low as four through a periphery‐core strategy. Crystallographic analysis confirms the formation of a bowl‐shaped structure. The multiple heteroatoms alter the molecular electronic structure, thus resulting in the distinct aromaticity when compared with its all‐carbon congener. The electron‐rich buckybowl shows a strong interaction with the electron‐deficient fullerene C60 by forming a 1 : 1 complex in toluene.
