通过施加电场，获得了具有侧氟化苯基的苯基噻吩衍生物的排列自组装纤维。这些纤维聚集体由于π共轭部分的堆积而表现出光导特性。相反，不含氟取代基的苯基噻吩衍生物在电场作用下形成不排列的纤维。氟化分子的介电各向异性在光导纤维聚集体的排列中起着关键作用。
Aligned self-assembled fibers have been obtained for a phenylbithiophene derivative with a laterally fluorinated phenylene group by the application of electric fields. These fibrous aggregates exhibit photoconductive properties due to the stacking of the π-conjugated moiety. In contrast, a phenylbithiophene derivative without fluoro substituents forms unaligned fibers under electric fields. The dielectric anisotropy of the fluorinated molecule plays a key role in the alignment of photoconductive fibrous aggregates.
