- Compound, organic luminescent material and organic electroluminescent device
-
The invention provides a compound as shown in a general formula (I), which has a mother structure of sym-triphenyl substituted anthracene, is high in bond energy among atoms, has good thermal stability, is beneficial to solid-state accumulation among molecules, is large in bandwidth, has a light-emitting region in a blue light region, is high in light-emitting intensity, and has a proper energy level with adjacent levels. And injection and migration of excitons are facilitated. When the compound is used as a blue light host material in a luminescent layer, the driving voltage of an organic electroluminescent device can be effectively reduced, the luminous efficiency is improved, and the service life is prolonged. The invention also provides an organic electroluminescent device and a display device containing the compound of the general formula (I).
