Incorporation of α,β′‐pyridine into a [26]hexaphyrin(1.1.0.1.1.0) frame resulted in formation of 29,33‐diaza‐A,D‐di‐p‐benzi[26]hexaphyrin (A,D‐di‐p‐pyrirubyrin), which acquires a strictly planar conformation with two nitrogen pyridine atoms directed to the center of the macrocyclic core. The mode of α,β′‐pyridine incorporation results in efficient 26‐electron π‐conjugation, as shown by the clear spectroscopic...
