Abstract

Regardless of its position within the DNA film, cross‐linked daunomycin (DM) is efficiently reduced electrochemically, indicating that the electron transfer exhibits a shallow distance dependence. Upon the introduction of an intervening cytosine–adenine (CA) mismatch, the electrochemical response is dramatically attenuated (shown schematically). Therefore, the DNA double helix can facilitate long‐range electron transfer, but only in the presence of a well‐stacked pathway.
