导电聚合物自组装纳米器件

Self-assembled conducting polymer nanometer scale devices

导电聚合物自20世纪70年代以来得到了广泛的研究.然而,关于聚合物纳米器件的研究则鲜有报导.从纳米尺度上研究导电聚合物,不仅有利于从更小的尺度上解析聚合物的光电性能、电荷传输机理,也可以将导电聚合物和纳米电子学有机地结合起来,发展聚合物纳米电子学的研究.文章介绍了最近由胡文平等[1,2]采用自组装的方法构筑的聚合物纳米器件和在纳米器件中观察到的一些有趣的现象.

The possibility of combining conjugated polymers with nanometer scale devices （nanodevices） to incorporate their propertiesis discussed. This approach combines the highly topical disciplines of polymer electronics and nanoelectronics to create a new sub-direction of polymer nanoelectronics, which can serve as a tool to probe the behavior of polymer molecules at the nanometer/molecular level, and contribute to the clarification of the transport mechanisms in conjugated polymers. We investigate this combination using a family of linear and conjugated polymers, poly （p-phenylene-ethynylene）s with thiolacetate functionalized end groups as an exam ple.
