The 14π-electron system of anthracene has been merged with the unsaturated -1,2-difurylethene to form a macrocycle(s) with the retained local conjugation of all incorporated subunits that were substantially modulated with a redox activation, opening a global delocalization involving all integrated aromatics. In addition, the edge modulation of acene via the attachment of a specific isomer of the conjugated system gives steric confinements that are characteristic of small macrocycles, forcing substantially short C(H)···O electrostatic interactions that are documented spectroscopically with the support of X-ray analysis.
蒽的14π电子体系已与不饱和-1,2-二呋喃乙烯合并，形成一个大环，其中所有并入的亚基保留了局部共轭，这些共轭通过氧化还原活化得到了显著调节，开启了涉及所有整合芳烃的全局离域。此外，通过连接共轭体系的特定异构体对并苯进行边缘调节，产生了小大环特有的空间限制，迫使形成了短得多的C(H)···O静电相互作用，这在X射线分析的支持下通过光谱记录了下来。
