1.Synthesis of macrocyclic TTF derivatives for molecular nanowiresMacrocyclic derivatives were synthesized and combined with acceptor molecules to obtain conducting molecular assembly nanowires. Thiomethyl, BEDT-TTF and BEDO-TTF type molecules were synthesized Thiomethyl-type molecules formed nanowires and used for the subject 2 and 3 described below. BEDT-TTF type molecule was extensively studied and it was found that the molecule formed organogels and that its iodine complex formed nanodot structures. The molecules with three TTF units were also synthesized and subjected to form Langmuir-Blodgett(LB) films. Complex with C60 successfully formed LB films.2.Wiring techniqueMechanism of wire formation was evaluated and the best condition for forming wires was fixed. We found that gel and wire formation are closely related to each other. Best on this, molecular design was carried out for novel wire formation. Hybrid structure with gold nanoparticles was prepared and the detailed electrical properties were evaluated.3.Structural evaluation of nanowire networksStructure of nanowire network was evaluated by probe maicroscopes. It was found that the C60-macrocyclic TTF showed surface-pressure induced charge-transfer transition in thin film form.
