Description

technical field

[0001] The invention relates to the field of organic electroluminescence, in particular to a quinoline derivative, its application and an organic electroluminescence device. Background technique

[0002] In 1998, Professor Ma Yuguang of Jilin University doped poly-N-vinylcarbazole (PVK) with an osmium complex [Os(CN) 2 (PPh 3 ) 2 bpy] prepared an electrophosphorescent device (Synthetic Metals, 1998, 94:245-248). In the same year, Thomson and Forrest collaborated to dope the phosphorescent material platinum octaethylporphyrin (PtOEP) on 8-hydroxyquinoline aluminum (Alq 3 ) as the light-emitting layer of the electroluminescent device, the internal quantum efficiency and external quantum efficiency are increased to 23%, 4% (Nature, 1998,395:151-154; Appl.Phys.Lett.,1999,75:4 -6). Since then, organic light-emitting devices based on phosphorescent metal complexes have developed rapidly. Different from traditional organic small molecules and conjugated polyme...
