4,4′-二甲氧基氧化偶氮苯（PAA）是一种有机化合物。它在固态是白色粉末，加热时形成液晶态。它是已知的且容易制备的液晶之一，在液晶显示器的发展用起着重要作用。 它的液晶范围在118 °C到136 °C之间。固态到向列的相变温度为118℃，向列到向同性液体的相变温度为136℃。

Comme tous les cristaux liquides, il présente des mésophases dans une certaine gamme de température, il passe de l'état cristallin à la phase nématique à 118 °C et de la phase nématique à la phase liquide isotrope à 136 °C. Étant l'une des premières substance mésogènes connues et de par la facilité de sa synthèse, le PAA a joué un rôle important dans le développement de l'affichage à cristaux liquides.pement de l'affichage à cristaux liquides.
, para-Azoxyanisole (PAA) is an organic, aro … para-Azoxyanisole (PAA) is an organic, aromatic compound. In a solid state, it appears as a white powder, but when heated it forms a liquid crystal. As one of the first known and most readily prepared liquid crystals, PAA has played an important role in the development of liquid crystal displays. Its liquid crystal range is from 118 °C to 136 °C. The solid to nematic transition is at 118 °C and the nematic to isotropic liquid transition at 136 °C. to isotropic liquid transition at 136 °C.
