Abstract
Insulated molecular wire made from conducting polymer and insulated cyclic molecule, and conducting polymer nanofiber in which conducting polymers simultaneously assembled are molecular nanowires with nm-scale diameter and expected to be applied for molecular nanodevices. Here, we explain electric properties of isolated these nanowires. In particular, since the crystallinity of conducting polymer nanofiber can be controlled by changing fabrication conditions, the relation between microscopic structure and electric properties was investigated and the property of field-effect transistor was evaluated. Furthermore, the relation of topology and electric properties of nanofiber and nanofiber composite film embedded in conventional polymer were studied. From these results, we considered possibilities of these materials for the nanotechnology.
