Patent ID: 11145824

Abstract:
The present disclosure relates to an organic photoelectric functional material, a method for the same, usage of the same, and a light-emitting device. The organic photoelectric functional material has electroluminescence and electron transportation properties. The organic photoelectric functional material is selected from a group consisting of compounds represented by formula I and formula II, and combinations thereof. If the organic photoelectric functional material is used as an electroluminescence material, light emission thereof can be adjusted by modifying a quinoline moiety thereof with a substituent, and a luminous range thereof is about 345 nm to about 700 nm. If the organic photoelectric functional material is used as an electron transporting-type host material which, together with hole-type host material, forms an exciplex co-host system, a light-emitting device prepared therefrom has improved stability and efficiency when compared with a light-emitting device prepared from a traditional host material.
