摘要：

Better molecular wires could result from an improved understanding of the effects of nucleotide sequence on the efficiency of excess electron transfer in DNA. Negative charge migrates in duplex DNA from a photoexcited aromatic amine residue (D; see figure) to 5-bromo-2′-deoxyuridine (BrU) in a sequence- and orientation-dependent manner.
