A novel compound represented by the general formula (I), and a nematic liquid crystal composition incorporating the same.
A compound represented by the general formula (I) can be produced industrially extremely easily, as shown in the examples, displays superior compatibility with current general purpose host liquid crystals as a nematic phase, and also shows little crystal precipitation at low temperatures. Moreover, by addition of a small amount of such a compound to a host liquid crystal, the liquid crystal temperature range at low temperatures can be effectively widened without any significant worsening of the various characteristics of the liquid crystal material. Consequently, a compound of the present invention is an extremely useful liquid crystal material which is suitable for various liquid crystal display elements which require a broad operating temperature range.
一种由通式(I)表示的新化合物,以及包含该化合物的向列相液晶组合物。如示例所示,由通式(I)表示的化合物可以极其容易地在工业上生产,并且作为向列相具有优异的与当前通用主机液晶的兼容性,在低温下也显示出很少的晶体沉淀。此外,通过向主机液晶添加少量此类化合物,可以有效地扩大液晶在低温下的温度范围,而不会显著恶化液晶材料的各种特性。因此,本发明的化合物是一种极其有用的液晶材料,适用于需要广泛操作温度范围的各种液晶显示元件。
