A decahydronaphthalene derivative represented by general formula (I), a liquid-crystal composition containing the derivative; and a liquid-crystal element containing the composition. The decahydronaphthalene derivative, which is a novel compound, can be extremely easily produced even on an industrial scale as shown in Examples. When added to a base liquid crystal in a small amount, the derivative not only widens the nematic-phase temperature range but can improve various properties of the liquid-crystal material. The derivative has excellent compatibility with base liquid crystals currently in general use as nematic liquid crystals. Therefore, it is suitable for use in various liquid-crystal display elements required to operate in a wide temperature range and is extremely useful as a material for liquid crystals.
一种由通式(I)表示的十氢萘衍生物,一种含有该衍生物的液晶组合物;以及一种含有该组合物的液晶元件。十氢萘衍生物是一种新型化合物,可以非常容易地生产出来,甚至可以进行工业化生产,如实施例所示。当少量添加到基础液晶中时,该衍生物不仅能扩大向列相的温度范围,还能改善液晶材料的各种性能。该衍生物与目前普遍用作向列液晶的基质液晶具有良好的兼容性。因此,它适用于需要在较宽温度范围内工作的各种液晶显示元件,作为液晶材料极为有用。
