The present invention relates to organic electroluminescent devices comprising metal complexes of the formula (1), and to metal complexes for use in organic electroluminescent devices. Depending on the metal used, the metal complexes are useful as emitters, as matrix materials, as hole-blocking materials, as electron-transport materials, and in other functions in the OLED. Organic electroluminescent devices comprising the metal chelate complexes described herein result in significant improvements in the organic electroluminescent device, in particular with respect to the lifetime, the efficiency and the stability to heating, particularly in green- and blue-phosphorescent electroluminescent devices.
本发明涉及包含式(1)金属络合物的有机电致发光器件,以及用于有机电致发光器件的金属络合物。根据所用金属的不同,金属络合物可用作发光体、基质材料、空穴阻断材料、电子传输材料以及有机发光二极管中的其他功能。包含本文所述金属螯合物的有机电致发光器件可显著改善有机电致发光器件的性能,特别是在使用寿命、效率和加热稳定性方面,尤其是在绿色和蓝色磷光电致发光器件中。
