Design, preparation, and characterization of novel ET salts with supramolecular assembly. Sheet, chain, and pore structures based on difluorotetraiodobenzene
To control the donor/anion ratio of an ET (= bis(ethyl enedithio)tetrathiafulvalene) salt, an anionic supramolecular assembly was designed. The supramolecular assembly based on 1,4-difluoro-2,3,5,6-tetraiodobenzene (DFTIB) and the bromide anion thus afforded an ET salt with desired 3:1 donor/anion ratio, while it also gave three other salts with unexpected structures. These salts showed semiconductive behaviors in the resistivity.
