| titleOfInvention | A kind of isoindole derivative, its use and OLED device containing the same |
| abstract | The present invention provides an isoindole derivative, its use and an OLED device comprising the same. The isoindole derivative is a compound having the structure of formula I. The OLED device comprises: an anode, a cathode and an organic thin film layer arranged between the anode and the cathode, the organic thin film layer at least contains a light emitting layer, a hole injection layer and a hole transport layer; The hole injection layer includes a host material and a dopant material, and the dopant material is selected from one or a combination of at least two of the above isoindole derivatives. The isoindole derivatives provided by the invention are electron acceptors, which can be used for doping the hole injection layer of the OLED device, and have the advantages of reducing the turn-on voltage of the OLED device and improving its lifespan and luminous efficiency. |
