A liquid crystal compound represented by the following general formula (1):
wherein R is a linear alkyl group having 6 to 12 carbon atoms, X and Y are both a hydrogen atom, or one of them is a hydrogen atom and the other is a fluorine atom, m is an integer of 0 to 5, n is an integer of 1 to 5, and C* is an asymmetric carbon atom.
Since the liquid crystal compounds of the present invention have an anti-ferroelectric phase or a ferrielectric phase and the anti-ferroelectric phase or a ferrielectric phase has a highly practical phase sequence and wide temperature range, they are of great industrial value.
由以下通式(1)表示的液晶化合物:
其中 R 为具有 6 至 12 个碳原子的直链烷基,X 和 Y 均为氢原子,或其中一个为氢原子,另一个为
氟原子,m 为 0 至 5 的整数,n 为 1 至 5 的整数,C* 为不对称碳原子。
由于本发明的液晶化合物具有反
铁电体相或
铁电体相,而反
铁电体相或
铁电体相具有高度实用的相序和较宽的温度范围,因此具有很高的工业价值。
