用于液晶取向的掺偶氮类染料的光诱导取向膜
Azo-dye dopant Photo-Induced Aligning Layer for Liquid Crystal Cells
【摘要】 介绍了一种使用聚酰亚胺和偶氮类染料进行液晶光诱导取向技术,深入研究了代号为SY04包含两个偶氮基团的新偶氮类染料·通过对取向膜偏振吸收光谱的分析,讨论了这种混合材料光诱导取向机理·由于聚酰亚胺良好的成膜性使得这种光诱导取向膜具有很好的稳定性,偶氮类染料的引入使得液晶表面取向更加有序,从而获得了响应快速,电光特性优良的液晶盒·这种取向膜材料同时具有很好的热稳定性及抗紫外稳定性·
【Abstract】 A photo-induced alignment technique using polyimide and azo-dye dopant was described.The new azo-dye material named SY04,which contained two azo groups,was studied.The photo-induced alignment mechanism was investigated by analyzing the polarized absorption spectra. In order to improve the stability of the photo-aligned film,a sort of polyimide material was mixed.The new azo-dye dopant aligning layer produced a high qualitative surface alignment,which resulted in fast response performance and good electro-optical performance.This alignment material provided good thermo-stability and was stable under weak UV irradiation as well.
