摘要

摘要利用线偏振紫外(LP-UV)光对准查尔酮类表面修饰聚酰亚胺薄膜，对液晶分子进行垂直对准。低紫外光照射可引起查尔酮衍生物的二聚化或异构化。查尔酮衍生物上的长烷基链呈同向异性排列，lc分子也是如此。

Application of Photo-Alignment Technique through the Modification of the Polyimide Surface with Chalcone Derivatives to Vertically Aligned LCD

Abstract The photo-alignment with the linear-polarized UV (LP-UV) light was applied to the surface modified polyimide film with chalcone derivatives for the vertical alignment of liquid crystal molecules. The LP-UV light irradiation caused either dimerization or isomerization of chalcone derivatives. The long alkyl-chains attached on the chalcone derivatives were aligned homeotropically and so are LC-molecules.
