合成一类新型标题化合物,此类单体液晶在结构上有着独特的新颖性,未见文献报道。以卤代物为起始原料,通过Suzuki反应合成5种结构类似的单体液晶,对其结构进行标定,并对目标液晶单体的性能进行测试。此类单体液晶有着较宽的向列相范围,可以用来拓宽混合液晶的低温向列相范围。此外,此类单体液晶有着较高的光学各向异性(Δn)及适宜的介电各向异性(Δε),可以作为一款通用液晶参与混合液晶的配置。
Synthesis of a new type of title compounds, such monomer liquid crystal has a unique novelty in the structure, has not been reported in the literature. Halogenated products were used as starting materials to synthesize five kinds of monomeric liquid crystals with similar structure by Suzuki reaction. Their structures were calibrated and the properties of the target liquid crystal monomers were tested. Such a monolithic liquid crystal has a wide range of nematic phase, which can be used to broaden the range of low temperature nematic phase of the mixed liquid crystal. In addition, such a monolithic liquid crystal has a high optical anisotropy (Δn) and a suitable dielectric anisotropy (Δ∈), and can be used as a general-purpose liquid crystal in a hybrid liquid crystal configuration.
