手性液晶的研究——Ⅵ.2,5-二苯基吡啶类

摘要: 设计合成了(+)-2-4-(2′-甲基丁氧基)苯基-5-(4″-烷氧基苯基吡啶和(+)-2-4-烷氧基苯基-5-4′-(2″-甲基丁氧基)苯基吡啶两个系列共七个手性液晶化合物。进行了结构分析,确证其结构。它们具有右旋近晶相、宽的相变温度、稳定性好等性能。

Abstract: Two series of seven chiral liquid crystal compounds (d)AmPAPPr, AP(d)AmPPr were synthesized. Thier structure were shown with analysis. These compounds possess valuable properties such as right handed low specific rotatory power, broad temperature range of chiral smectic C phase, high stability etc., and latently practical value.
