    • For aggregates of 3, the CT band is at 740 nm (1.68 eV), while the CT band in 7 is found at 640 nm (1.94 eV). In a first approximation, the difference in the energy of the CT bands (0.26 eV) scales with the difference between reduction potentials of the acceptor units (0.22 eV). This allows one to predict that the CT absorption in aggregates of 1 should be ∼0.15 eV above that of 7, i.e., at ∼2.1 eV or 590 nm, which overlaps with the normal absorption of aggregate.

    • note
    • It should be noted here that differences in rate constants for the charge separation and recombination rates between the three studied compounds in the same solvent cannot be directly related to the supramolecular structure. The observed differences originate from the different acceptor strength induced by the substituents on the bay position of the perylene bisimide moiety.
