有机发光材料及其制备方法和含该材料的有机电致发光器件
摘要：
本发明涉及发光材料领域，具体涉及一种有机发光材料及其制备方法和含该材料的有机电致发光器件。本发明的有机发光材料，其为下述结构式中的任意一种：上述结构式中：R为苯基或联苯基；Ar1和Ar2各自独立地选自取代或未取代的C6-31的芳基、或者取代或未取代的C12-30的杂芳基。本发明通过引入芳基胺获得了空穴注入能力/传输能力，高功率效率、长寿命。由本发明的机发光化合物制备的有机电致发光器件具有极佳电流效率和功率效率以及长寿命。本发明的有机发光化合物的制备方法，重复性好，产率高。
摘要（英）：

The invention relates to the field of luminescent materials, and concretely relates to an organic luminescent material, a preparation method thereof, and an organic electroluminescent device containing the material. The organic luminescent material is represented by any one of structural formulas shown in the description; and in the structural formulas, R is a phenyl group or a biphenyl group, andAr1 and Ar2 are respectively independently selected from a substituted or non-substituted C6-31 aryl group, or a substituted or non-substituted C12-30 heteroaryl group. Arylamine is introduced to obtain a hole injection/transport capability, a high power efficiency and a long life. The organic electroluminescent device produced from the organic luminescent material has an excellent current efficiency, an excellent power efficiency and a long life. The preparation method of the organic luminescent material has the advantages of good repeatability and high yield.
