equipped with a heating stage. The smectic–isotropic (Sm-I) phase transition curve and the Cr-Sm transition curve behave in normal manner in the phase diagram. Analytical and spectral data confirm molecular structures of novel homologues. The average thermal stability for smectic is 139.42°C and the mesogenic phase length ranges from 3.5°C to 79.6°C. Mesogenic properties are compared with the structurally
摘要 为了理解和确定分子结构对液晶性质和液晶度的影响,已经合成了完全近源性的新型热致液晶 (LC) 的查尔酮基同系物衍生物。同源系列由 12 个(C1 到 C16)同源物组成,在整个本系列中都没有致线虫特征。近晶相的织构为近晶-A或近晶-C的扇形或棒状。相变温度和热致数据通过配备加热台的光学偏光显微镜确定。近晶-各向同性 (Sm-I) 相变曲线和 Cr-Sm 相变曲线在相图中以正常方式表现。分析和光谱数据证实了新型同源物的分子结构。近晶的平均热稳定性为 139.42°C,介晶相长度范围为 3.5°C 至 79.6°C。介晶特性与结构相似的已知系列进行比较。
