synthetic pathway to a cyclophane bearing two benz[a]anthracene units connected at the 5 and 7 positions through two naphth-1,4-diyl groups was developed, and its structure was confirmed by X-ray structure analysis. Because of structural constraints, the two naphthyl groups are distorted from planarity and the bonds connecting them to the benz[a]anthracene units are bent significantly. The UV–vis and
建立了通向带有两个通过两个萘-1,4-二烷基连接在5和7位的两个苯并[ a ]蒽单元的环烷的合成途径,并通过X射线结构分析证实了其结构。由于结构上的限制,两个萘基从平面度上变形,并将它们连接至苯并[ a ]蒽单元的键显着弯曲。环烷的紫外-可见光谱和荧光光谱与相应的单体多环芳烃7-(1-萘基)苯并[ a ]蒽的光谱相比发生了红移。
