To control the donor/anion ratio of an ET (= bis(ethylenedithio)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.
为了控制 ET(=双(亚乙基二
硫代)四
硫富
戊烯)盐的供体/阴离子比例,我们设计了一种阴离子超分子组装体。因此,基于 1,4-二
氟-2,3,5,6-四
碘苯 (DFTIB) 和
溴阴离子的超分子组装物产生了一种供体/阴离子比例为 3:1 的 ET 盐,同时还产生了另外三种具有意想不到结构的盐。这些盐在电阻率方面表现出半导电性。
