The present invention provided optically active alcohols represented by the general formula: ##STR1## wherein R.sup.1 indicates an alkyl or alkyloxy group having a carbon number of 1-18, and A indicates a phenyl or a biphenyl group; or a phenyl or biphenyl group having a halogen atom or a cyano group. The alcohols are intermediates of optically active materials useful for components of liquid crystal materials for liquid crystal display elements having quick response.
本发明提供了一种光学活性醇,其通式表示为:##STR1## 其中,R1表示碳数为1-18的烷基或烷氧基,A表示苯基或
联苯基;或者是带有卤素原子或
氰基的苯基或
联苯基。这些醇是光学活性材料的中间体,可用作液晶显示元件的液晶材料组分,具有快速响应的特点。
