| Abstract(in English) | Tetrathiafulvalene(TTF)molecules have a tendency to assemble in one-dimensional stacks through π-π overlaps along the stacking direction. The TTF system is easily oxidized by chemical or electrochemical procedures, and the regular stack of partially oxidized TTF molecules provides partially filled one-dimensional π-band structures resulting in metallic electrical conduction properties. Therefore, a large number of organic metals and superconductors have been reported in the forms of cation radical salts and charge transfer(CT)complexes using electron donor molecules based on TTF. In this study, we report the structures and electric properties of molecular nanofibers composed of TTF derivatives and tetrafluorotetracyanoquinodimethane(F_4TCNQ)as an organic acceptor. We synthesized TTF derivatives having chiral and hydrogen-bonding side chains. The UV spectra of TTF derivatives and their F_4TCNQ complexes were measured by the diffuse reflection method. CT complexes exhibited the absorption band in 700-900 nm, which is assigned to the F_4TCNQ anion radicals. The IR spectra of TTF derivatives and the complexes were measured by the ATR method. The CT complexes exhibited a broad absorption band from 2500 to 3000 cm^<-1>, which was attributable to the charge transfer between electron-donating TTF derivatives and electron-accepting F_4TCNQ. The nanofibers of(TTF derivative)(F_4TCNQ)were fabricated on Si and quartz substrates by cast techniques. The surface morphology was examined by AFM. |
