Description

technical field [0001] The invention relates to a luminescent material and a preparation method thereof. Background technique [0002] Metal-organic complexes play an important role in functional materials such as luminescence, magnetism, catalysis, and hydrogen storage due to their structural diversity and tunability. . Among them, metal complexes with strong fluorescent light-emitting ability have very important potential application value and can be developed as new light-emitting functional materials. To realize full-color display in organic electroluminescent devices (OLEDs), materials that emit red, green, and blue light are essential. Among them, 8-hydroxyquinoline aluminum is a typical green light-emitting material, which has been successfully assembled into OLED organic light-emitting devices. However, in recent years, research on high-performance green light devices has been achieved by optimizing the structure of the device or using high-performance host materi...
