在与4，4 [prime or minute]-bipyridine络合时，具有两个π-电子耦合结合位点的稠合卟啉锌络合物的环状二聚体在第二客体结合中显示出强的负协同性，以允许逐步形成1：1和1：2包合络合物。
Upon complexation with 4,4[prime or minute]-bipyridine, a cyclic dimer of a fused porphyrin zinc complex, having two pi-electronically coupled binding sites, shows a strong negative cooperativity in the second guest binding, to allow stepwise formation of 1 : 1 and 1 : 2 inclusion complexes.
