Optically active oxirane derivatives containing a mesogenic molecular unit are suitable as dopes in liquid-crystal mixtures. They give liquid-crystalline ferroelectric phases having short response times and electroclinic phases having large electroclinic coefficients. A further advantage is that they induce a helix of very small pitch, so that they are also suitable for helix compensation in LC mixtures.
含有介向分子单元的光学活性环氧衍生物适用于液晶混合物中的掺杂剂。它们产生具有短响应时间的液晶铁电相和具有大电致伸缩系数的电致伸缩相。另一个优点是它们诱导非常小的螺旋周期,因此它们也适用于液晶混合物中的螺旋补偿。
