摘要：

The precursor EP-AN was synthesized by means of the polymerization between aniline and Biphenol-A epoxy which is industrial products. Then the cinnamate groups were attached to the chains of the hydroxyl-containing precursor to prepare EP-AN-CI, which is the potential photo alignment layer for liquid crystal. They were characterized by H-1-NMR, FTIR, and differential scanning calorimetry(DSC). EP-AN-CI was spin-coated on a ITO glass substrate from chloroform solution, resulting in a thin film, then though the linearly polarized polymerization (LPP) it was changed into photo alignment layer. LC cells of a 10 mum-thick were assembled via a capillary action. The photomocrographies were obtained which can be used to explain that EP-AN-CI can be applied in photo alignment layer.
