    • Many other bis(amine) derivatives with conjugated bridging groups of similar (or even shorter) length also show little or no separation between first and second molecular oxidation events. For example, see: (a) Lambert, C.; Nöll, G. J. Am. Chem. Soc. 1999, 121, 8434.

    • Since the nitrogen atoms of PDIs lie on nodal planes of both HOMO and LUMO (for example, see: Kazmaier, P. M.; Hoffmann, R. J. Am. Chem. Soc. 1994, 7769684), we have considered systems in which donors are linked through aryl groups to the N,N′ positions as nonconjugated.

    • Although this compound does not exhibit a well-separated CT-type band, the electronic spectrum deviates considerably from the sum of those of its constituent donor and acceptor, indicating significant ground-state coupling

    • From the transient data it is unclear whether a secondary charge-separation process occurs to form a D′·+ · · · D-A·--D · · · D-type state. This could be either because the two charge-separated states have rather similar spectra or because the difference in the electron-donor strengths of primary and secondary donor moieties is insufficient to overcome the electrostatic interaction between hole and electron in a charge-separated state where the hole is localized on the primary donor
