Ionic liquid-stabilized nanoparticles of charge transfer-based conductors

Well-dispersed nanoparticles of molecule-based conductors, namely TTF·TCNQ and TTF[Ni(dmit)2]2, have been prepared in organic solution using 1-butyl-3-metylimidazolium tetrafluoroborate as a stabilizing agent. TTF·TCNQ nanoparticles (prepared at room temperature) exhibit sizes ranging from 2 to 5.5 nm, whereas those of TTF[Ni(dmit)2]2 (prepared at −80 °C) are larger (sizes in the 16–45 nm range). Nanoparticle powders have been characterized by X-ray diffraction, X-ray photoelectron spectroscopy, and by transport measurements.
