16. 4-nP using nicotinaldechyde instead of isonicotinaldehyde, and other derivatives are also known.
17. As described later, heating the solutions of these oligomers at high temperatures will cause their decompositions. It can be presumed that the reaction temperature affects the yields of oligomers.

20. The chemical shift difference Δδ is equal to δ(oligomer) - δ(parent porphyrin monomer).
21. OEP protons of perpendicular-type oligomers show no upfield shifts (see ref 7).
22. 2P plane (adjacent to each other) and the deshielding by another OEP ring is more effective than in the αβ form.
