A liquid crystal compound with high helical twisting power, a method for preparing the same, and a liquid crystal composition containing the same. The liquid crystal compounds include cyclic group chain structures similar to the liquid crystal to serve as the core structure, and multi-ring structures of natural alcohol with optical activity, such as alcoholates of terpenol, borneol, cinchonidine, quinine, or derivatives thereof. As a result, the liquid crystal composition containing the liquid crystal compounds can filter out light of specific wavelengths from incident light due to optical activity and high helical twisting power thereof.
一种具有高螺旋扭曲功率的液晶化合物,其制备方法以及含有该化合物的液晶组合物。该液晶化合物包括与液晶相似的环状群链结构作为核心结构,以及带有光学活性的天然醇的多环结构,例如萜醇、
蒎烯醇、
奎宁、
奎宁衍
生物等的醇盐。因此,含有该液晶化合物的液晶组合物能够通过光学活性和高螺旋扭曲功率从入射光中过滤出特定波长的光。
