15. In these experiments, the concentration of the secondary electron acceptor was kept small enough (50 μM for methyl and benzyl viologen) in relation to DABCO ([DABCO] = 6.2 mM and 10 mM for NI and NDI, respectively) to preclude direct quenching of the imide triplet state by the bipyridine derivatives. Under these conditions, the imide radical is quantitatively "scavenged" by the viologen.

20. f)). (21) The mode of binding of cationic naphthalene imide and diimide derivatives (the pendant groups on the imide nitrogens are a quaternary alkylammonium substituents) to DNA has been reported in ref 7. Using a combination of viscometric titrations, along with circular dichroism and UV/vis spectroscopies, Yen et al. have shown that the compounds interact strongly with DNA through intercalative interactions.
21. We thank the reviewer for bringing this possibility to our attention.
