61. The aforementioned redox potentials indicate the absence of significant electronic interaction between the electroactive chromophores in 18, 23, 25, and 26.
62. We would like to point out that the missing data points in Table 2 could not be determined within the 100 ps time-resolution of the apparatus. The complementary picosecond-resolved transient absorption measurements infer indeed lifetimes that are either close to or within the 100 ps apparatus time-resolution.

68. The reactivity scheme of 4a, 18, and 23 - comparing the steady-state and time-resolved fluorescence experiments - fails to reveal substantial differences. Therefore, only time-resolved fluorescence lifetime measurements will be discussed for triads 25 and 26. In addition, the presence of two exTTF moieties imposes notable difficulties on convoluting the individual contributions in the steady-state emission experiments.
69. The intramolecular decay rates in triad 26 do not differ notably from those of dyad 18.
70. Additional proof for an intramolecular charge-recombination stems from a set of experiments, conducted with different laser power and different dyad concentrations: Decreasing the radical-pair concentration in various increments by up to 65% failed to lead to any notable changes in the charge-recombination kinetics.
