    • Stoichiometric binding constants for multiple site ligands are related to microscopic binding constants by means of statistical factors. See Figure 2 and reference [20], p. 20.

    • note
    • It is generally accepted that intermolecular binding of a divalent receptor (two binding sites) to a monovalent substrate (unique binding site) is positively cooperative if α is larger than 1, it is non-cooperative or statistical if α is equal to 1, and it is negatively cooperative if α is smaller than 1. See reference [20], Chapter 2. α is calculated by dividing the value of the statistically corrected binding constant of the second interaction by that of the first interaction.

    • 11. In this case, α is calculated by dividing the value of the statistically corrected binding constant of the first interaction by that of the second interaction. The system is said to be positively cooperative if α is smaller than 1.

    • -1 for the stability constant of the ternary complex predict that at 0.5 equivalents of DABCO, the ratio of ternary/sandwich complex should be 15/85, 1/99, and 11/89 for 5 a, 5 b, and 5 c, respectively.

    • note
    • Experiments to distinguish the structure of the complexes by ESI mass spectrometry gave only molecular ions corresponding to the free porphyrins. This is a common result for supramolecular assemblies based on the coordination of zinc-oligoporphyrins with aza ligands. All attempts to grow crystals were unsuccessful.
