We can investigate extrinsic charge transport property by using thin film transistors. In addition, the single-crystalline objects will lead us to investigate the intrinsic charge transporting properties of organic semiconducting materials. In the case of crystalline semiconducting polymers, 1-dimensional(1-D) nanostructured objects are fabricated via proper methods such as membrane wetting method and self-assembly in a dilute solution. The aspect ratio of nanowire was modulated with the fabrication method. The internal morphology of elaborated nanowires was investigated by grazing incidence X-ray diffraction and transmission electron microscopy in detail. For instance, transmission electron microscopy and selected area electron diffraction analyses of polymer nanowires made from diketopyrrolopyrrole(DPP)-based copolymer reveal its single-crystalline nature. Highly salient is the fact that the polymer chain axis within the single crystals is parallel to the longitudinal axis of the wire, and the π-π stacking direction is perpendicular to the wire growth direction. High-performance DPP-containing polymers were employed to fabricate the nanowire-based FETs to investigate the intrinsic charge transport property of the polymer, which was compared with those in thin film transistors.
