AI Technical Summary
Current organic light emitting devices face challenges in enhancing performance, lifetime, and efficiency due to limitations in materials used for the organic thin film, particularly in terms of hole injection, hole transfer, electron blocking, and electron injection processes.
A heterocyclic compound represented by Chemical Formula 1 is introduced, which can function as a hole injection material, hole transfer material, hole blocking material, light emitting material, electron transfer material, or electron injection material, specifically designed to form layers in organic light emitting devices, optimizing electron transfer and hole blocking capabilities through its azine-based substituents and fluorene group.
The compound reduces driving voltage, enhances light efficiency, and improves the thermal stability and lifetime of the device by adjusting the band gap and T1 value, thereby improving electron transfer and hole blocking properties.
