合成了以酰胺键为中心桥键的三芳环1,3,4-噻二环系共8个新化合物。液晶性质测试证明它们均为具有高相变温度和宽相变范围的稳定的液晶化合物。
A total of 8 new compounds were synthesized by the 1,3,4-thiadicyclic ring system with amide bond as the central bridge. Liquid-crystalline properties proved to be stable liquid crystal compounds with high phase transition temperature and a wide range of phase transitions.
