The present invention relates to novel organic compounds comprising at least two different selections selected from the group consisting of N-phenyl carbazole, dibenzofuran, dibenzothiophene, triphenylene, aza-(N-phenyl carbazole), aza-dibenzofuran, aza-dibenzothiophene, and aza-triphenylene. The compounds are useful for organic light-emitting diodes. The compounds are also useful for charge-transport and charge-blocking layers, and as hosts in the light-emissive layer for organic light emitting devices (OLEDs).
本发明涉及一种新的有机化合物,包括至少两种不同的选择,选择自N-苯基咔唑、二苯并呋喃、二苯并噻吩、三苯基乙烯、氮杂-N-苯基咔唑、氮杂二苯并呋喃、氮杂二苯并噻吩和氮杂三苯基乙烯组成的群体。这些化合物可用于有机发光二极管。这些化合物还可用于电荷传输和电荷阻挡层,并作为有机发光器件(OLEDs)的发光层中的宿主。
