A polyimide comprises a reaction product of at least one dianhydride and at least one diamine, wherein the at least one diamine contains a pendent mesogenic group. A method for inducing a predetermined orientation of a liquid crystal material is also disclosed. The method includes applying an alignment layer material to a substrate and buffing the alignment layer material, thereby providing an alignment layer with a pre-tilt angle, wherein the alignment layer material is a reaction product of at least one dianhydride and at least one diamine, wherein the at least one diamine contains a pendent mesogenic group.
一种聚酰亚胺包括至少一种二酐和至少一种二胺的反应产物,其中至少一种二胺含有一个悬垂介原基。还公开了一种诱导液晶材料预定取向的方法。该方法包括将配位层材料应用到基底上,并对配位层材料进行磨光,从而提供具有预倾斜角的配位层,其中配位层材料是至少一种二酐和至少一种二胺的反应产物,其中至少一种二胺含有悬垂介原基。
