Cu（I）介导的meso，meso '-1，3-丁二烯桥连的Zn（II）双卟啉与各种胺的环化有效地提供了meso，meso'-吡咯桥连的Zn（II）双卟啉。观察到这些双卟啉的分子内电子相互作用。通过Suzuki-Miyaura偶联反应合成了一种星型卟啉五聚体。
Cu(I)-mediated annulation of meso,meso'-1,3-butadiyne-bridged Zn(II) diporphyrin with various amines efficiently provided meso,meso'-pyrrole-bridged Zn(II) diporphyrins. Notable intramolecular electronic interactions in these diporphyrins were observed. A starburst porphyrin pentamer was synthesized via Suzuki-Miyaura coupling of N-bromophenylpyrrole-bridged diporphyrin and meso,meso'-diborylated porphyrin.
