a U‐shaped handle. While UH/H itself shows a bicontinuous cubic (Cubbi) phase, UH/H in the presence of pyrene molecules as an external guest forms a hexagonal columnar (Colh) phase without phase separation. Interestingly, even when the pyrene molecules were covalently attached to UH/H (UPy/Py), the molecule exhibited a Colh phase, with a similar columnar geometry to that of UH/H mixed with pyrene molecules
我们报告了偶然发现的新型液晶(LC)分子U H / H的异常行为,该分子包含U形手柄。虽然U H / H本身显示出双连续立方(Cub bi)相,但在of分子作为外部客体的情况下,U H / H形成了六方柱状(Col h)相,没有相分离。有趣的是,即使the分子共价连接到U H / H(U Py / Py),该分子仍表现出Col h相,其柱状几何形状与U H / H相似与pyr分子(1-4当量)混合。该结果意味着,无论如何将the部分结合到LC系统中,所得材料均表现出具有柱状几何形状的相似分子组装体。这一发现很有趣,因为U H / H和pyr分子似乎不具有特定的相互作用或形状互补性以形成圆柱状组装体,就像在U Py / Py的情况下一样。©2018 Wiley Periodicals,Inc.J.Polym。科学,A部分:Polym。
