To provide a compound, when the compound has both a high clearing point and a low crystallization temperature, having a wide temperature range of a liquid crystal phase and also an excellent solubility in other liquid crystal compounds, and further having general physical properties necessary for the compound, namely, stability to heat, light and so forth, a suitable optical anisotropy and a suitable dielectric anisotropy. A compound is represented by formula (1):
wherein, for example, Ra and Rb are alkyl having 1 to 10 carbons; A1, A2, A3 and A4 are 1,4-phenylene; Z1, Z2, Z3 and Z4 are a single bond or alkylene having 1 to 4 carbons; and m, n, q and r are independently 0, 1, or 2, and a sum of m, n, q and r is 1, 2, 3 or 4.
提供一种化合物,当该化合物具有较高的澄明点和较低的结晶温度时,其液晶相具有较宽的温度范围,在其他液晶化合物中也具有极佳的溶解性,并进一步具有该化合物所需的一般物理性质,即对热、光等的稳定性,适当的光学各向异性和适当的介电各向异性。一种化合物用式(1)表示:
其中,例如,Ra 和 Rb 是具有 1 至 10 个碳原子的烷基;A1、A2、A3 和 A4 是 1,4-亚苯基;Z1、Z2、Z3 和 Z4 是单键或具有 1 至 4 个碳原子的亚烷基;m、n、q 和 r 独立地为 0、1 或 2,m、n、q 和 r 之和为 1、2、3 或 4。
