    手性液晶的研究——Ⅶ.苯基嘧啶类铁电液晶

    • 摘要: 合成了四个系列共十四个化合物,测定了它们的相变温度和相态,对部分化合物进行了电滞回线和螺距的测试,并比较了结构和性能的关系。其中(d)AmPA′Pm(Ⅱ)和(d)HpPA′Pm(Ⅳ)为室温铁电液晶,AP(d)Hp′Pm(Ⅲ)为胆甾相液晶,对产物进行了初步的混合配方探索。

       

      Abstract: Four different series of chiral pyrimidine compounds were synihesizcd, and their mesomorphic properties were studied. The specific rotation of all these compounds were also determined. The series of two exhibited have wide temperature range chiral smectic C phases at room temperature. The hysteresis loops showed with these compounds prove their ferroelectricity.
