DNA‐mediated charge transport across adenine tracts was monitored by using a fast radical probe that is part of the bridge ( N 6 ‐cyclopropyladenine, blue). As described by J. K. Barton and co‐workers in their Communication on page 5731 ff., this trap, placed at each base across the A tract, is oxidized by the distal rhodium photooxidant (orange) with equal yield over a distance of 5 nm. These results are consistent with complete charge delocalization across the DNA bridge.
