This paper describes the preparation and thermal properties of a homologous series of 4-alkoxyphenyl 4-thiocyanatophenyl terephthalates. The homologous series shows nematic and smectic A phases commencing from the pentyloxy homolog. The smectic A phase is immiscible with the smectic A phase of polar liquid crystals having a terminal cyano group. Interestingly, the smectic B phase is also formed from the hexyloxy homolog, while the compound has a polar group at the terminal position.
本文介绍了 4-烷氧基苯基-4-硫氰基苯基对苯二甲酸盐同系物的制备方法和热性能。该同系物从戊氧基同系物开始出现向列和共晶 A 相。共晶 A 相与具有末端氰基的极性液晶的共晶 A 相互不相溶。有趣的是,B 相也是由己氧基同族体形成的,而化合物的末端位置有一个极性基团。
