| abstract |
The invention relates to a high-efficiency light-emitting phosphorescent material and application thereof to an organic photoelectric device. An aromatic heterocycte 6-5 matched bidentate complex is adopted as an auxiliary ligand, and through a chemical hybridization manner, a novel heavy metal ligand complex is obtained, thus the organic photoelectric material can be suitable for multi-color phosphorescent application, has excellent heat stability, electronic stability and easy-to-prepare characteristics, and is especially suitable for large flat-panel display screens and organic light-emitting devices for high-brightness lighting application. |
