The first fully connected aromatic carbaporphyrin dimer () and its bis-Pd complex () that bear a rigid naphthalene motif as an internal strap were synthesized. These dimers consisted of two aromatic carbaporphyrins that shared a naphthalene motif. The π-electron conjugation of the obtained macrocycles was proposed to have two separated local 22 π-electron pathways and a 34 π-electron pathway. Their weak aromaticity was fully supported by H NMR spectroscopy, NICS values, ACID calculations, and ICSS plots.
合成了首个带有刚性萘基序作为内部链的全连接芳族碳卟啉二聚体（）及其双钯配合物（）。这些二聚体由两个共享萘基序的芳族碳卟啉组成。所获得的大环的π电子共轭被认为具有两条分开的局部22π电子路径和一条34π电子路径。它们的弱芳香性得到了核磁共振氢谱、核独立化学位移值、原子化电荷密度计算和感应电流密度屏蔽图的充分支持。
