一、结构晶体通常是指原子结构按一定模型排列,并具晶面的结晶固体而言。在一定温度范围内具有各向异性并能象结晶固体一样对光发生反应的液体也具有晶体特性。这种液态晶体受到温度变化以及机械、电子和化学刺激时会形成一定形式的色变谱。第一批液晶是1883年澳大利亚植物学家F·赖尼特泽发现的.他提出,胆甾醇苯酸酯具有两个熔点,当加热到145℃时便变为混浊液,继续加热到179℃时液体就变清。一年后德国科学家 O.菜曼对此进行了深入的研究。他发现,混浊液说明了分子的排列情况并体现了晶体的光学性质。
First, the structure of the crystal is usually refers to the atomic structure arranged according to a certain model, and crystal surface crystalline solid terms. Liquids that have anisotropy over a range of temperatures and react with light as crystalline solids also have crystalline properties. This liquid crystal undergoes some form of discoloration when subjected to temperature changes and mechanical, electrical and chemical stimuli. The first liquid crystals were discovered by the Australian botanist F. Reneezeet in 1883. He proposed that cholesteryl benzoate has two melting points and becomes cloudy when heated to 145 ° C and continues to heat to 179 ° C When the liquid becomes clear. A year later, the German scientist O. Manman conducted an in-depth study. He found that the turbidity solution illustrates the arrangement of molecules and reflects the optical properties of the crystals.
