Charge transport through molecular structures is interesting both scientifically and technologically. To date, DNA is the only type of polymer that transports significant currents over distances of more than a few nanometers in individual molecules. For molecular electronics, DNA derivatives are by far more promising than native DNA due to their improved charge‐transport properties. Here, the synthesis of several unique DNA derivatives along with electrical characterization and theoretical models is surveyed. The derivatives include double stranded poly(G)–poly(C) DNA molecules, four stranded G4‐DNA, metal–DNA hybrid molecular wires, and other DNA molecules that are modified either at the bases or at the backbone. The electrical characteristics of these nanostructures, studied experimentally by electrostatic force microscopy, conductive atomic force microscopy, and scanning tunneling microscopy and spectroscopy, are reviewed.

基于DNA的衍生物的合成和电荷迁移的测量进展

通过分子结构的电荷传输在科学和技术上都是有趣的。迄今为止，DNA是唯一一种可以在单个分子中跨超过几纳米的距离传输大量电流的聚合物。对于分子电子学来说，DNA衍生物由于其改善的电荷传输特性而比天然DNA更有前景。在这里，调查了几种独特的DNA衍生物的合成以及电学表征和理论模型。衍生物包括双链聚（G）-聚（C）DNA分子，四链G4-DNA，金属-DNA杂合分子线，以及在碱基或骨架上修饰的其他DNA分子。这些纳米结构的电学特性，通过静电力显微镜进行了实验研究，
