23. The 97.5% of excited light leading to the C singlet state is the lower limit for energy migration efficiency as a function of excitation wavelength and is obtained at excitation wavelengths corresponding to the maxima of A and B subunits.
24. This approach is made possible by the supramolecular nature of 1 as evidenced in Figures 2 and 3.
25. See SI for further experimental details. However, the ET rate constants calculated by the quantum yield method should be considered with care, because of the large uncertainty of quantum yields determinations, particularly in the case of low quantum yields.
26. 2 and 1 is considered. The reported values consider one acceptor, as is the case in 1.
27. 2C quantum yield data is significantly lower than that calculated by Förster theory. The origin of this disagreement could lie in the nature of the excited state of the C dye. Such a state is expected to have a significant CT nature, involving the dimethylamino group, so the donor-acceptor distance value used in the Förster calculation is probably shorter than the effective one.
