| titleOfInvention | an organic light-emitting device |
| abstract | The invention provides an organic light-emitting device, which relates to the technical field of organic electroluminescence. The hole transport region of the present invention includes a first hole transport layer and a second hole transport layer, the present invention applies the triarylamine derivative represented by formula I to the first hole transport layer, and the triamine represented by formula II is used in the first hole transport layer. The compound is used in the second hole transport layer, and the combination of the two materials is applied to the organic light-emitting device at the same time, which improves the transport efficiency of holes and electrons in the device, and effectively blocks holes and electrons in the light-emitting layer. , to achieve the maximum recombination of carriers, thereby greatly improving the luminous efficiency of the device and the service life of the device, and has good application effects and industrialization prospects. It can be widely used in panel display, illumination light source, organic solar cell, organic photoreceptor or organic thin film transistor and other fields. |
