ABSTRACT We report a newly rod like calamatic liquid crystalline materials, which are constructed by the self-organization of a rod-like carboxylic acid derivative based on Schiff base ester as the linking group with tert butyl tail group. A newly series of 4-(tert-butyl) phenyl 4-((4-alkoxybenzylidene) amino) benzoate with different alkyl chain spacer (n = 1 to 8, 10, 12, 14, 16, and 18) were synthesized
图形摘要摘要我们报告了一种新的棒状光滑液晶材料,它是由基于席夫碱酯作为连接基团的棒状羧酸衍生物与叔丁基尾基团自组装构成的。合成了具有不同烷基链间隔物(n = 1 到 8、10、12、14、16 和 18)的新系列 4-(叔丁基)苯基 4-((4-烷氧基亚苄基)氨基)苯甲酸酯及其通过差示扫描量热法和偏光显微镜研究了介晶性质。本系列中的所有同源物均以对映方式显示中间相。SmC-SmA 的热稳定性为 137.5 °C。所有化合物均通过光谱和元素分析表征。
