摘　　要：文章选取液晶高分子偶氮苯为研究对象,采用偏振可见光诱导偶氮苯分子发生择优取向。通过光显微镜对其液晶基元的取向进行了研究,研究结果表明交联的偶氮苯分子的液晶基元沿着入射光的偏振方向取向。最后笔者将这种取向化的液晶薄膜应用到发光聚合物中,研究发现这种取向的薄膜可以调控发光高分子材料的取向有序结构的形成,并且可以诱导发光聚合物进行取向发光。In this study, the liquid crystal polymers were chose as objectives. The polarized light was used to induce the azobenzene orientation, and the orientation was studied by the cross-section polarized microscope. The results indicate that the liquid crystal unit aligned along the incident light polarization. In addition, the oriented liquid crystal films were used to induce the orientation of the light emitting polymers. The results indicate that the crystal films can control the formation of highly ordered light emitting polymers and can induce the polarized light emitting of polymers.
