Pyriporphyrin – A Porphyrin Homologue Containing A Built‐in Pyridine Moiety

Abstract

Abstract Pyriporphyrin 1 (6,11,16,21‐tetraaryl‐22‐aza‐ m ‐benziporphyrin), the simplest homologue of 5,10,15,20‐tetraarylporphyrin can be constructed by replacement of one of the pyrrole rings of 5,10,15,20‐tetraarylporphyrin with a pyridine moiety, linked to the macrocycle through α,α′‐carbon atoms.
