Synthesis and Characterization of a Directly Linked N‐Confused Porphyrin Dimer

There's nothing confusing about the dimer (see picture) that forms from N-confused porphyrin! The dimer was obtained as a directly β–β-linked structure through a simple acid-catalyzed condensation reaction of the monomeric macrocycles, and the electronic interaction between the porphyrin subunits was studied for both the free-base form and for the bis(nickel(II)) complex.
