The present invention relates to phosphorescent organic light-emitting diodes (OLEDs) comprising a hole-transporting or a hole-transporting and an electron-blocking layer comprising N,N,N′,N′-tetraaryl-phenylene-3,5-diamine compounds bearing in position 1 of the phenylenediamine core a 9H-fluorenyl substituent. The inventive compounds are useful as hole-transporting and electron-blocking layer matrices in phosphorescent OLEDs.
本发明涉及
磷光有机发光二极管(OLEDs),其中包括一个传输正空穴层或传输正空穴和电子阻挡层,该层包括在
苯二胺核心的1位上带有9H-
芴基取代基的N,N,N',N'-四芳基苯基-3,5-二胺化合物。这些创新化合物在
磷光OLEDs中作为传输正空穴和电子阻挡层基体是有用的。
