Amphiphilic bis-tetrathiafulvalene (bis-TTF) annulated macrocycles (1) were designed from the viewpoints of supramolecular chemistry and surface science in order to construct a variety of nanostructures based on molecular conductors. Electrically active low-dimensional nanostructures such as molecular-assembly nanodots, nanowires and nanorings were fabricated from the charge-transfer (CT) complexes of donor 1 by spin-coating and Langmuir-Blodgett techniques. CT complex of bis (methylthio)-substituted derivative (1a) formed oriented molecular-assembly nanowires on mica surface, whose typical dimensions were 2.5×50×>1,000 nm. The nanowire growth directions were consistent with the directions of hexagonal lattice of K⁺ sites on the mica surface. Ethylenedithio-substituted derivative (1b) had an ability to form a new redox-active organogel. Chemical oxidation of donor 1b yielded size-controllable nanodot structures by applying spin-coating technique. The diameter of nanodots (20∼800 nm) depended on the rotation speed of the spinner. Conductance of carrier dopped nanodots was three or four orders of magnitude higher than those of neutral molecular-assembly nanostructures.
