Electron transfer through DNA : The electron‐transfer dynamics of i‐motif DNA conjugated with pyrene (Py) and anthraquinone (AQ) has been investigated by fluorescence up‐conversion and transient absorption spectroscopic methods. Electron transfer (see red arrows) in i‐motif DNA is more efficient than in duplex DNA, suggesting that i‐motif DNA can be used as electron carrier in nanoelectronic devices.
