Optically active liquid crystal compounds represented by general formula (I), wherein A and B each represents -0-, II, III or IV, wherein '-' represents a direct bond, one of R, and R, represents a straight-chain alkyl group, and the other represents an alkyl group containing an asymmetic carbon atom or an alkoxyalkyl group having an asymmetric carbon atom and an ether bond, with the asymmetric carbon atom having one of -CH3, -CN, and -Cl are disclosed. Many of these liquid crystal compounds are revealed to show a SmC phase in a wide temperature range around room temperature and perform a rapid response.
本发明公开了由通式(I)表示的光学活性液晶化合物,其中 A 和 B 各自代表-0-、II、III 或 IV,其中'-'代表直接键,R 和 R 中的一个代表直链烷基,另一个代表含有不对称碳原子的烷基或具有不对称碳原子和醚键的烷氧基烷基,不对称碳原子具有-CH3、-CN 和-Cl 中的一种。 其中许多液晶化合物在室温附近的宽温度范围内显示出 SmC 相,并且反应迅速。
