An optically active compound of the general formula (1) useful as a chiral dopant, and use thereof for a liquid crystal composition,
the above optically active compound having a remarkably large helical twisting power (HTP) of as large as 50 or more and having a property that the helical pitch induced decreases in length with an increase in temperature, so that the optically active compound has an excellent value as a chiral dopant for a nematic liquid crystal.
一种可用作手性掺杂剂的通式(1)的光学活性化合物及其在液晶组合物中的用途、
上述光学活性化合物的螺旋扭曲力(HTP)非常大,可达 50 或更大,并且具有螺旋间距随温度升高而减小的特性,因此该光学活性化合物作为向列液晶的手性掺杂剂具有极高的价值。
