range compared to the 1,3,4-oxadiazole calix[4]arene derivatives. The cone-shaped calixarene-based LCs with terminally substituted alkyl chains are packed into columns with enhanced intermolecular interactions. Moreover, the 1,3,4-oxadiazole calix[4]arene derivatives show deeper blue emissions compared to the 1,3,4-thidiazole calix[4]arene derivatives in solution as well as in thin films. The thermal
一类新的蓝色发光的超分子的液晶锥体或碗形的化合物是从取代的1,3,4-恶二唑和1,3,4-噻二唑与含有取代的烷氧基侧链酯基团内置(-OC合成4 ħ 9,–OC 8 H 17)在杯[4] arene的下边缘。这些超分子化合物通过偏振光学显微镜(POM),差示扫描量热法(DSC),热重分析(TGA),高温X射线衍射(XRD),循环伏安法(CV)和光物理行为研究进行了研究。观察到,与1,3,4-恶二唑杯[4]芳烃衍生物相比,1,3,4-噻二唑杯[4]芳烃基衍生物在较宽的热范围内更能稳定六方柱状相。 。具有末端取代的烷基链的圆锥形杯形芳烃基LC填充到具有增强的分子间相互作用的色谱柱中。此外,与溶液和薄膜中的1,3,4-噻二唑杯[4]芳烃衍生物相比,1,3,4-恶二唑杯[4]芳烃衍生物显示出更深的蓝色发射。合成的碗形超分子衍生物的热和光物理行为非常依赖于杯[4]芳烃下缘的末端取代的烷氧基链。由于它们
