Abstract
Official abstract text for this publication.
A liquid crystal alignment material and a display panel containing the same are provided. The liquid crystal alignment material includes an additive and pillar[n]arene. The additive includes a first group, a second group, and a third group. The second group is attached between the first group and the third group. The third group has a polarity. The pillar[n]arene includes n benzene rings and n is a positive integer. The benzene rings are bonded to each other and define a cavity. The pillar[n]arene is attached to the first group of the additive. The display panel includes the liquid crystal alignment material and a liquid crystal molecule.
First claim
Opening claim text (preview).
The invention claimed is: 1. A liquid crystal alignment material, wherein the liquid crystal alignment material is presented by Formula (1): wherein each X is phenylene or cyclohexylene. 2. A display panel, comprising: a liquid crystal alignment material and a liquid crystal molecule; wherein the liquid crystal alignment material is presented by Formula (1): wherein each X is phenylene or cyclohexylene; wherein five benzene rings of in the Formula (1) are bonded to each other and define one cavity; and wherein the liquid crystal molecule is intercalated in the cavity by an intermolecular force.
