Nanoparticles of molecule-based conductors
Résumé
State of the art molecule-based conductors that have been isolated as nanoparticles are reviewed. Research efforts in this field is justified by their insolubility and low vapour pressure, making their integration into electronic devices difficult. Their availability as nanoparticles would allow researchers to study their properties at the nanoscale and as stable dispersions, offering new opportunities for processing. Molecular conductors and superconductors that have been isolated as nanoparticles are: TTF[middle dot]TCNQ, TTF[Ni(dmit)2]2, TTFCl0.77 and TTFBr0.59, (BEDT-TTF)Cl0.66 and (BEDT-TTF)2Br, (TMTSF)2ClO4 and (TMTSF)2PF6. Nanoparticle formation and shape depend on the stabilizing agent used for controlling the growth: ionic liquids, long-chain ammonium salts or neutral liquid polymers. The conductivities of the nanoparticle powders are reported.
