The reaction between a naphthylbipyrrole-containing hexaphyrin-type expanded porphyrin and copper acetate affords a bench-stable dicopper(II) complex. UV-vis spectroscopy, cyclic voltammetry, and X-ray crystallographic analysis measurements provide support for the conclusion that this complex displays aromatic features. A weak antiferromagnetic exchange interaction between the binuclear copper(II) ions is evidenced by variable-temperature electron paramagnetic resonance and by fitting of the bulk magnetic susceptibility to a dimer model, yielding J = -5.1 cm.
含萘基联吡咯的六卟啉型扩展卟啉与醋酸铜之间的反应生成了一种在实验台上稳定的二铜（II）配合物。紫外可见光谱、循环伏安法和X射线晶体学分析测量结果支持了该配合物具有芳香特征这一结论。变温电子顺磁共振以及将体磁化率拟合到二聚体模型的结果证明了双核铜（II）离子之间存在弱反铁磁交换相互作用，得到J = -5.1 cm。
