Specifically substituted aza-dibenzofurans and aza-dibenzothiophenes of formula (I) and their use in electronic devices, especially electroluminescent devices. When used as charge transport material, charge blocker material and/or host material in electroluminescent devices, the specifically substituted aza-dibenzofurans and aza- dibenzothiophenes may provide improved efficiency, stability, manufacturability, or spectral characteristics of electroluminescent devices and reduced driving voltage of electroluminescent devices. In formula (I) Y is S or 0; one of X1-X8 is N; another X1-X8 is C-L(R9)-[X9X10X11]Ring; and the remaining X1-X8 are CR1-CR8 wherein R1-R8 are independently H, alkyl, alkenyl, aryl, etc.
具体替代的aza-二苯并呋喃和aza-二苯并噻吩的化学式(I)及其在电子器件中的应用,特别是在电致发光器件中。当作为电荷传输材料、电荷阻挡材料和/或宿主材料在电致发光器件中使用时,具体替代的aza-二苯并呋喃和aza-二苯并噻吩可能提供改善电致发光器件的效率、稳定性、可制造性或光谱特性,以及降低电致发光器件的驱动电压。在化学式(I)中,Y为S或0;X1-X8中的一个是N;另一个X1-X8是C-L(R9)-[X9X10X11]Ring;其余的X1-X8是CR1-CR8,其中R1-R8独立地为H、烷基、烯基、芳基等。
