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.
