A kind of organic electroluminescent material and its application |
| abstract |
The invention relates to an organic electroluminescent material and its application. The organic electroluminescent material takes a pyrene ring as the center, introduces a substituent containing a carbazole group into the 1 and 6 positions of the pyrene ring, and introduces a substituent containing a cyano group into the pyrene ring. The substituents of the group are introduced into the 3 and 8 positions of the pyrene ring. Carbazole is an electron-rich group with good hole transport ability. As a strong electron-withdrawing group, the cyano group can promote intramolecular charge transfer and make the molecular dipole moment Biasing can greatly improve the performance of the material. Pyrene is a rigid condensed ring structure with good thermal stability. The above excellent properties make the organic electroluminescent material have good film stability and exciton transport ability, and can be used as a blue light emitting material in the field of organic electroluminescence. |
