Charge transfer through DNA is of great interest because of the potential of DNA to be a building block for nanoelectronic sensors and devices. The photochemical reaction of 5‐halouracil has been used for probing charge‐transfer processes along DNA. We previously reported on unique charge transfer following photochemical reaction of 5‐bromouracil within four‐base π‐stacks in Z‐DNA. In this study, we incorporated a guanosine instead of a deoxyguanosine into Z‐DNA, and found that electron transfer occurs in a different mechanism through four‐base π‐stacks.
