Provided are a polymerizing liquid-crystalline compound of formula (1).
In formula (1), Q
1
to Q
4
each independently represent a formula (2), a hydrogen atom, a halogen atom, an alkyl group or the like; at least two of Q
1
to Q
4
are a formula (2) and may differ from each other. In formula (2), A independently represent a 1,4-cyclohexylene group, a 1,4-phenylene group or the like; X independently represents a single bond, an alkylene group or the like; Z represents a single bond, —COO—, —OCO— or the like; n indicates an integer of from 0 to 3; p represents any one polymerizing group of formulae (P1) to (P8); W represents a hydrogen atom, a halogen atom, an alkyl group or the like. When Q
1
and Q
2
are both hydrogen atoms and when Q
3
and Q
4
are both formula (2), then p must not be (P8).
提供了一个化学式为(1)的聚合液晶化合物。在公式(1)中,Q1到Q4各自独立地表示公式(2),氢原子,卤素原子,烷基或类似物;至少两个Q1到Q4是公式(2),并且可以彼此不同。在公式(2)中,A独立地表示1,4-环己烯基,1,4-苯基或类似物;X独立地表示单键,烷基或类似物;Z表示单键,—COO—,—OCO—或类似物;n表示0到3的整数;p表示公式(P1)到(P8)中的任何一种聚合基团;W表示氢原子,卤素原子,烷基或类似物。当Q1和Q2都是氢原子,当Q3和Q4都是公式(2)时,则p不能是(P8)。
