    • note
    • A(D*A) is defined as the ratio of the photoluminescence intensities of the acceptor chromophore after excitation of the isolated acceptor chromphore and after excitation of the donor chromophore of the dyad (DA), after correction for the optical density.

    • .+ radical cation were determined at 0.98 and 1.74 eV by measuring a 1/1 mixture of 4TP and TCNE (oxidizing agent which has no absorptions in the infrared region) by PIA spectroscopy.

    • All reported intensities of the PIA bands (-ΔT/T) were obtained by recording the PIA spectrum at 275 Hz and pumping the sample at 528 nm with 25 mW.

    • note
    • The frequency dependence shows the presence of long-lived species by the decay of -ΔT at low frequencies together with a region at high frequencies where the slope of -ΔT vs frequency approaches zero, indicating the simultaneous presence of short-lived species. Note that the PIA spectrum itself is measured at 275 Hz, which is already in the latter region.

    • note
    • This estimate is probably an upper limit to the actual internal reorganization energy in 4TsC and 4TdC, as a positive charge will delocalize over a large π-conjugated system to result in in a small structural deformation and reorganization energy.
