| abstract |
The present invention provides an organic compound, the structure of which is shown in formula I or II, wherein X 1 , X 2 , X 3 and X 4 are independently single bonds, oxygen, sulfur, nitrogen-containing groups or carbon-containing groups ; R 1 ‑R 10 is independently hydrogen, C 1 ‑C 10 alkyl, C 6 ‑C 40 aryl or C 6 ‑C 40 heteroaryl; or any two of R 1 ‑R 10 adjacent to them The bonded carbon atoms together form a ring structure. The invention also provides the application of the organic compound in electronic devices. By adopting the organic compound of the present invention, OLEDs can be made to have very good power efficiency, very long lifespan, and low operating voltage. |
