AI Technical Summary
The performance of existing organic electroluminescent materials in terms of efficiency, lifetime and voltage still needs to be improved, especially the performance of blue light host materials is not perfect enough to meet the needs of high-performance OLED devices.
By using a composition with a specific composition, including two compounds of Formula I and one compound of Formula II, or one compound of Formula I and two compounds of Formula II, as the light-emitting layer material of an organic electroluminescent device, a high-performance organic electroluminescent device can be prepared through the specific design of the composition's components.
The prepared organic electroluminescent devices have low driving voltage, high current efficiency, long lifespan, and excellent overall performance.
