that form supramolecular liquid crystals (LCs) from phase‐segregated two‐dimensional (2D) crystals. The unique double‐, triple‐, and quadruple‐layer packing structure of fullerenes in the 2D crystals leads to different smectic supramolecular LC phases, and novel LC phase transitions were observed upon changes in the fullerene packing layer number in the 2D crystals. Interestingly, by combining the
我们在此报告了一系列由四嵌段模拟的偶氮苯组成的[60]富勒烯二聚体,它们由相分离的二维(2D)晶体形成超分子液晶(LC)。2D晶体中富勒烯独特的双层,三层和四层堆积结构导致了不同的近晶超分子LC相,并且在2D晶体中富勒烯堆积层数变化时观察到了新的LC相变。有趣的是,通过将LC特性与2D晶体相结合,这些材料显示出出色的电子迁移率,约为10 -3 cm 2 V -1 s -1,尽管它们的富勒烯含量相对较低。我们的结果提供了一种新颖的方法来处理2D晶体层的厚度,并在光电器件中具有广阔的应用前景。
