| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In recent years, the field of molecular electronics has been getting a lot of interest because of its potential to realize small devices and complex applications. In the field of nanotechnology, the assembly of molecules that produce a unique electrical or magnetic property has been investigated as an alternative to top-down methods. Molecular conductors, such as tetrathiafulvalene (TTF) and 7,7,8,8-tetracyanoquinodimethane (TCNQ), are one of the bottom-up methods in which molecules self-assemble to form the organic material. One-dimensional columnar structures are formed when two molecules are stacked separately, and they are known to exhibit high electrical conductivity. In this study, we investigated the effect of C3-symmetry on the electrical conductivity. We synthesized a C3-symmetric TTF derivative (MeS-TTF-Ts) to develop conductive nanofibers and apply them to devices. In this molecule, π-conjugated and hydrogen-bonded moieties were placed in multiple locations to form a one-dimensional structure and stabilize the structure. Conducting nanofibers were prepared by casting DMSO solution of (MeS-TTF-Ts)(F4TCNQ)3 complex, which is a charge transfer complex with acceptor molecules, on mica substrate. The electrical conductivity of the nanofibers was 10-2 S/cm. | |
