LUMO‐level dependent : Chemically modified DNA molecules containing 2 ′ ‐deoxyuridine (dU) derivatives with various LUMO energy levels have been synthesized to manipulate electron‐transfer efficiencies. By arranging thymidine, the dU derivatives, and 5‐fluoro‐2 ′ ‐deoxyuridine in order of their LUMO levels, the efficiency and the directionality of photoinduced electron transport in DNA could be regulated.
