    • 25a dipole-dipole interaction between the neighboring PDI moieties i and i + 1 or i + 3 is expected to be very minor not only because of the larger interchromophoric distance (∼2.5 nm between their center-of-masses) but also due to the nearly perpendicular orientation of the main transition dipole moments of these chromophore pairs (β = 96°)

    • To calculate the exciton interaction for the dimer formed by PDI units i and i + 4, we have applied the formulae given in ref 25a to the geometry of the polymer drawn in Figure 3c and the PDI monomer absorption spectrum in Figure 4a
