The concise synthesis of C3-symmetrical [12]CPP-hexacarboxylate has been achieved through macrocyclization by the rhodium-catalyzed intermolecular cross-cyclotrimerization and subsequent reductive aromatization. C3-Symmetrical functionalization of CPP with highly polar alkoxycarbonyl groups enabled the structurally uniform nanotube assembly in the crystalline state through multiple hydrogen-bonding interactions giving a dimer followed by one-dimensional stacking.
通过铑催化的分子间交叉环三聚反应进行大环化以及随后的还原芳构化，实现了C3对称的[12]环戊二烯并菲六羧酸酯的简洁合成。CPP与高极性烷氧羰基的C3对称官能化使得在结晶状态下通过多重氢键相互作用形成结构均匀的纳米管组装体，形成二聚体，随后进行一维堆积。
