4-methoxybenzo- hydrazide [II]a and benzene-1,3,5-tricarbohydrazide [II]b were used as starting materials for the synthesis of these new derivatives. These compounds were identified by using elemental analysis, FTIR, 1H-NMR, 13C-NMR and mass spectroscopy. The liquid crystalline properties were examined by using differential scanning calorimetry and polarized optical microscopy. Compound 4-methoxy-N'
噻唑啉酮和三唑衍生物的新化合物已通过多步程序合成。4-甲氧基苯甲酰肼[ II] a和苯-1,3,5-三碳酰肼[II ] b被用作合成这些新衍生物的起始原料。这些化合物通过元素分析、FTIR、1 H-NMR、13 C-NMR和质谱进行鉴定。通过使用差示扫描量热法和偏光光学显微镜检查液晶性质。化合物 4-甲氧基-N'-(-5-(-4-methoxybenzylidene)-4-oxo thiazolidin-2-ylidene) benzohydrazide [V] b显示近晶 A (SmA) 中间相,而化合物 5-(2-(1-(4-硝基苯基) 亚乙基) 肼基) -3-(3-(5-(2-(1-(4-硝基苯基) 亚乙基))肼基)-4H-1,2,4-三唑-3-基)-5-(5-(2-(1-(4-硝基苯基)亚乙基)肼基)-4H-1,2,4-三唑- 3-yl) phenyl)-1H-1,2,4-triazole
