In this issue of Chem, Jishan Wu and colleagues provide the first examples of annulene-within-an-annulene (AWA) structures in which the inner and outer conjugated circuits are formally fully decoupled. Existing models of AWA aromaticity might need to be revised to account for the exceptional behavior of these novel structures.

芳香之谜：冠状大环中环芳烃的解偶联

在本期《化学》杂志上，吴继山及其同事提供了环内环戊烯（AWA）结构的第一个示例，其中内部和外部共轭电路在形式上完全解耦。可能需要修改现有的AWA芳香度模型，以解决这些新颖结构的异常行为。
