21. ox1 of 2 was determined by differential pulse voltammetry because of existence of the reactive pyridyl group and free meso-position. For electrochemical reaction of pyridine derivatives with porphyrins, see: Ruhlmann, L.; Lobstein, S.; Gross, M.; Giraudeau, A. J. Org. Chem. 1999, 64, 1352.
22. The DFT calculation indicates that 2 also takes a ruffled conformation (Figure S16). The structural difference in macrocycles between 2 and 4 only slightly influences the difference of the oxidation potentials.
23. The reason is not clear why 3 shows only two waves despite the close proximity of two porphyrins. The reduction waves for 4 have not been fully characterized due to their complicated features.
