摘要
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 an N,N,N′,N′-tetraaryl-phenylene-3,5-diamine or an N,N,N′,N′-tetraaryl-1,1′-biphenyl-3,3′-diamine matrix compound and to new N,N,N′,N′-tetraarylsubstituted m-arylene diamine compounds useful as hole-transporting and electron-blocking layer matrices in phosphorescent OLEDs.
