    • The "inside coordination" implies that a ligand approaches from the side of the neighboring chlorin moiety (and is, thus, close spatial proximity to it), while the "outside coordination" implies that a ligand approaches from the side opposite to the neighboring chlorin moiety (and is, thus, spatially distant from it). It was previously shown that only inside coordination for bis-porphyrins, and their subsequent chiral steric interactions, are responsible for supramolecular chirogenesis in these systems (for details see ref 3d).

    • Using the example of the bis-porphyrin tweezer system, it was shown previously that only the degenerate couplings contribute significantly to the induced optical activity (see ref 3a).

    • note
    • Some deviations from the equal probability and dihedral angle are possible due to the different degree of the steric interactions between the ligand's bulkiest substituents and the ethyl groups of the neighboring chlorin moiety at the a and b-positions.
