A new class of bowl-shaped supramolecular liquid crystals (LCs) is described derived from calix[4]arene substituted with 1,3,4-thiadiazole derivatives, inbuilt with Schiff base and ester on the lower rim and with an azo group on the upper rim with an alkyl side chain (–OC3H7, –OC8H17). In the present investigation, we have synthesized six new supramolecular-based derivatives having three linking units
描述了一种新的碗形超分子液晶(LC),其衍生自用1,3,4-噻二唑衍生物取代的杯[4]芳烃,其在下部边缘装有席夫碱和酯,在下部边缘带有偶氮基。带有烷基侧链的上轮辋(–OC 3 H 7,–OC 8 H 17)。在目前的研究中,我们合成了六种新的基于超分子的衍生物,在衍生物杯的下部边缘上具有三个带有取代的1,3,4-噻二唑环和可变的三取代侧烷氧基链的连接单元。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)和高温X射线衍射研究(XRD)进行了研究。所有合成的化合物在长波长紫外光下在溶液中均显示出良好的蓝色荧光。本发明的化合物有望在较宽的热范围内稳定六方柱状相。碗形杯形芳烃基LC填充到具有增强的分子间相互作用的色谱柱中。
