A new macrocyclic arene, dibenzofuran[3]arene, was synthesized, which could be conveniently transformed to an O-doped aromatic belt with a rigid ring-shaped structure and deep cavity. Moreover, the O-doped aromatic belt also showed a high HOMO energy and a narrow HOMO–LUMO gap experimentally and theoretically.

氧掺杂芳香带的合成与性能

合成了一种新的大环芳烃二苯并呋喃[3]芳烃，它可以方便地转化为具有刚性环状结构和深空腔的氧掺杂芳香带。此外，O掺杂芳香带在实验和理论上还表现出高HOMO能量和窄HOMO-LUMO能隙。
