    • The values of the binding constants could not be determined from this experiments due to relatively high concentrations, which were necessary to obtain reliable data on the stoichiometry: however, a binding constant of K, 2.5 × 106 M1 (bp) to calf thymus DNA was determined Supporting Information, Figure S1
    • 1 (bp) to calf thymus DNA was determined (Supporting Information, Figure S1).

    • In both cases an increase of absorption in the long-wavelength region of the spectrum, λ>440 nm, was observed at high ligand-to-duplex loadings q>5, which disappeared as further amounts of DNA were added. We attribute this behavior to formation of aggregates of 2 on the exterior of the duplexes, which results in enhanced scattering, but does not lead to precipitation of the ligand-DNA complexes
