[structure: see text] Polyenyne macrocycles with pi-extended [9]- and [12]radialene frameworks have been synthesized. These radialenes exhibit restricted rotation of the aromatic rings, and the D3- and D4-symmetric structures in solutions have been determined by dynamic NMR. The macrocyclic radialenes bear small to medium inner cavities, and the small cavity of the pi-extended [9]radialene can incorporate a silver cation.
[结构：见原文] 已合成出具有π-扩展[9] - 和[12] - 并苯骨架的多烯炔大环化合物。这些并苯表现出芳环的受限旋转，并且通过动态核磁共振确定了溶液中的D3 - 和D4 - 对称结构。大环并苯具有小到中等大小的内腔，π-扩展[9] - 并苯的小内腔可以容纳一个银阳离子。
