A novel amphiphilic TTF hexamer 1 with a flexible disk-like structure and strong self-aggregation properties has been synthesized. Nanowires fabricated from both 1 and its cation radical 1(.+) in CHCl3/hexane solutions have a hexagonal columnar structure. In contrast, drop-cast films of 1 and 1(.+) exhibit an edge-to-edge close-packed arrangement stacking vertical to the drop-cast surface, indicating stronger dictating effect of surface area for the nanostructure fabrication. The electric conductivity of the wire of1(.+) is 2 orders of magnitude higher than that of the film of 1(.+), reflecting the nostructured, one-dimensional morphology.
