We have synthesized series of amphiphilic bis-TTF annulated macrocycles 1-6 by using complementary routes involving deprotection-alkylation methods of monothiolate. These amphiphilic bis-TTF annulated macrocycles were designed from the viewpoints of (i) electrically active TTF units for realizing electrically conducting one-dimensional π-π stacks, (ii) ion recognition at the macrocyclic moiety, and (iii) two-hydrophobic alkyl chains to fabricate nanoscale thin films. Nanostructures such as molecular nanowires, nanodots of the charge transfer (CT) complexes of amphiphilic bis-(TTF)-annulated macrocycle 1 and 2,3,5,6-tetrafluoro-7,7,8,8-tetracyano-p-quinodimethane (F 4-TCNQ) were constructed. The nanowires are oriented to specific directions, by recognizing the potassium array on mica surface. The open-shell electronic structure of nanostructures was determined by electronic spectra. Other nanostructures such as nanodomains and nanodots in addition to molecular thin films were fabricated from CT complexes of 1-6 and organic or inorganic acceptor molecules.
