First TTF-based conductor nanoparticles by electrocrystallization

Well-dispersed spherical nanoparticles of the mixed-valence conductor TTFCl0.77 have been electrochemically grown on a platinum electrode in the presence of long-alkyl chains quaternary ammonium salts acting as both supporting electrolyte and protecting agent. The nanoparticles prepared at room temperature under galvanostatic conditions exhibit sizes ranging from 50 to 150 nm. Conducting molecule-based nanoparticles have been studied by X-ray diffraction, infrared and Raman spectroscopy. Their room-temperature conductivity has been measured to about 0.2 S cm−1.
