An optically active compound represented by formula (I):
 wherein R¹ represents an alkyl group having from 6 to 18 carbon atoms or an alkoxy group having from 6 to 18 carbon atoms; A represents
 represents a nitrogen-containing hetero-aromatic ring; n and m each represents 0 or 1; R² represents an alkyl group having from 1 to 12 carbon atoms; and C* is an asymmetric carbon atom. The compound of formula (I) exhibits excellent physicochemical stability, a low temperature range for the chiral smectic C phase when used either alone or in combination with other compounds, and a rapid response.
                            由式 (I) 代表的光学活性化合物:
 其中 R¹ 代表具有 6 至 18 个碳原子的烷基或具有 6 至 18 个碳原子的烷氧基; A 代表
 代表含氮杂芳香环;n 和 m 分别代表 0 或 1;R² 代表具有 1 至 12 个碳原子的烷基;以及 C* 是不对称碳原子。式(I)化合物具有优异的理化稳定性,单独使用或与其他化合物结合使用时,手性 Smectic C 相的温度范围较低,反应迅速。
