有机电致发光领域中的液晶材料

Liquid Crystal Materials in the Field of Organic Electroluminescence

综述了液晶材料在有机电致发光领域中应用的研究进展。主要围绕通过引进液晶基元提高有机载流子传输材料的迁移率和将液晶性同发光性相结合,制备直接发射偏振光的有机电致发光器件两方面内容进行评述。

In recent years, organic electroluminescence has attracted intense interest for display applications. With its great progress, a considerable variety of novel materials have been synthesized. There is increasing interest in liquid crystal materials because of their fluidity of liquid as well as the optically anisotropic of crystal. On one hand, the mobility of the material can be increased dramatically if the liquidcrystal groups are induced into the carrier transport materials. On the other hand, the polarized luminescence can be realized when the optically anisotropic of liquid crystal is combined with light emitting materials. In this paper, the research progress of liquid crystal materials in the field of organic electroluminescence is reviewed.
