Schematic energy diagram, illustrating the lowered S1 energy levels of the dimer, trimer and tetramer. The energies of the singlet states were taken as the peak maximum of the absorption spectra (Fig. 2b). The energies of the charge separated states were estimated from the redox potentials and are shown for the monomer in solid lines and dimer in dotted lines (Supplementary Table 5). The energies of the triplet states were taken from quantum mechanical calculations (Fig. 2b).
