Description

technical field

[0001] The invention relates to the technical field of organic luminescent materials, in particular to an orange luminescent material, a preparation method and a luminescent method thereof. Background technique

[0002] Against the backdrop of increasingly prominent global energy shortages, white organic light-emitting devices (White Organic Light-Emitting Devices, WOLEDs) are widely used due to their wide source of materials, high performance, and the ability to realize large-area flexible display and lighting. focus on. The performance of WOLEDs is comparable to fluorescent lamps and inorganic light-emitting diodes, but its manufacturing cost is lower. From an application point of view, WOLEDs are very attractive and are flat-panel light sources, unlike most light sources in use today.

[0003] In recent years, many Pt(II) complexes with high brightness emission have been used as fluorescent materials in organic light-emitting devices (OLEDs). Metallic pl...
