    • 1/2 is not a constant with respect to scan rates (v) ranging between 50 and 500 mV/s). However, a tendency toward reversibility was noticed in the presence of DNA. In any case, we note that these electrochemical results do not have any significant effect on the value of the ratio of binding constants.

    • note
    • The observed differences in the DNA-photocleavage efficiencies of these complexes do not seem to arise from differences in their light absorption abilities, since their molar extinction coefficients at 440 nm are found to be close to each other (log ε = 4.3 ± 0.2).
