| 摘 要： | 研究了金属酞菁化合物四（２，４－二甲基苯氧基）酞菁铜和四（２，４－二甲基苯氧基）酞菁镍在汽－液界面上的成膜特性，制备了相应的Ｌａｎｇｍｕｉｒ－Ｂｌｏｄｇｅｔｔ（ＬＢ）膜。利用紫外可见吸收及偏振紫外可见吸收谱，表征了ＬＢ膜中的酞菁分子主要以二聚体的形式相对于基片水平排列。以酞菁ＬＢ膜为取向层制成液晶盒，取向向列型液晶Ｅ＿７。通过偏光显微镜及锥光干涉系统，确定液晶分子在ＬＢ膜上的排列情况，并进行了电光测试，讨论了导致不同取向效果的机理。

| Abstract: | The paper discusses the characteristics of copper tetrakis-(2,4-di-methyl phe-noxy)phthalocyanine(CuPc)and nickel tetrakis-(2,4-di-methyl phenoxy) phthalocyanine(NiPc)on the gas-liquid interface. The corresponding Langmuir-Blodgett(LB) films were prepared.It was confirmed that phthalocyanine molecules would lie flat on the substrates in dimers by UV-Vis and polarized UV-Vis spectral method. The LB films were used to align nematic liquid crystal E_7.Under a polarized microscope and the conoscopic system,the align-ment of the liquid crystal was observed on the LB films.The electro-optieal measurement was carried out.The mechanism of alignment was also discussed. |
