orientational order parameters, bond conformations, and molecular dimensions. For the dimers in particular, the solute shapes were estimated from phase diagrams of the dimer/MBBA systems, the crystal structures were determined by X-ray diffraction, and the melting points and enthalpies of fusion were evaluated from DSC measurements. From the dimers, the so-called odd−even effect was clearly observed in not only
已经研究了以下低聚物液晶 (LC) 模型化合物的结构-性质相关性:单体,C6H5O(CH2)xCH3(x = 4 和 5);二聚体,C6H5O(CH2)xOC6H5(x = 3、4、5 和 6);和四聚体 C6H5O(CH2)xOC6H4O(CH2)xOC6H4O(CH2)xOC6H5(x = 5 和 6)。从溶解在向列溶剂 4'-甲氧基亚苄基-4-正丁基苯胺 (MBBA) 或对偶氮基苯甲醚 (PAA) 中的氘代模型化合物中观察到的氘核磁共振四极分裂通过最大熵法的旋转异构状态方案进行分析以产生取向有序参数、键构象和分子尺寸。特别是对于二聚体,溶质形状由二聚体/MBBA 系统的相图估计,晶体结构由 X 射线衍射确定,并且熔点和熔化焓由DSC测量评估。从二聚体中,不仅在取向顺序和分子...
