A compound, light-emitting layer guest material, organic electroluminescent device and display device |
| abstract |
The present application provides a compound of the general formula (I), which can be used in organic electroluminescent devices as a guest material for the light-emitting layer. The compound comprises a structure in which a natural heterocycle is coordinated with iridium (Ir), and can effectively control the emission wavelength of the compound. Using it as the guest material of the light-emitting layer is beneficial to improve the light-emitting efficiency and photostability of the organic electroluminescent device. In addition, the compound provided by the present application has a small molecular weight, and when it is applied to the light-emitting layer, the evaporation temperature is low, which is favorable for processing. The present application also provides a light-emitting layer guest material, an organic electroluminescent device and a display device comprising the compound of the general formula (I). |
