  在包含具有2-辛氧基尾巴的棒状外消旋联苯介晶的简单二元混合物系统中观察到宽蓝相范围†

  摘要：

  容易制备四个具有2-辛氧基尾和在苯环的内核位置具有不同取代基的简单和棒状外消旋联苯介晶。这些外消旋联苯液晶元的中间相通过可变温度XRD和POM的特征结构得到证实。通常，在加热和冷却过程中，将适当比例的手性添加剂S811或ISO（6OBA）2添加到这些外消旋联苯液晶元中，可以诱发立方BP 。有趣的是，BPIII（5–6 K）在高手性条件下很容易控制由单取代联苯液晶元和手性掺杂剂S811组成的混合混合物。另外，当化合物C 6 OBiPhI-OH与35 wt％S811在冷却过程中混合时，BPIII的形成温度接近室温（36°C）。混合体系中存在的20 K以上的稳定BP由手性掺杂剂ISO（6OBA）2组成，没有取代的联苯液晶元C n OBiPhI-H或二氟取代的C n OBiPhI-FF。值得注意的是，通过在联苯化合物C 6 OBiPhI-H中仅添加10 wt％具有高HTP的手性掺杂剂ISO（6OB
