Abstract
Photoinduced electron transfer between cyanobenzophenone substituted 2′-deoxyuridine (d CNBPU) and GG sequence on the same strand of duplex DNA was examined. It was found that 5′-GT CNBPU-3′ was a most effective sequence for the generation of guanine radical cation, showing that DNA oligomers containing d CNBPU are widely usable for the studies for DNA-mediated charge transport. By using 5′-GT CNBPU-3′ sequence, we observed a remarkable one direction hole transport.
