| titleOfInvention | Composite material and preparation method thereof, and quantum dot light-emitting diode |
| abstract | The invention belongs to the technical field of light-emitting device materials, and particularly relates to a composite material, a preparation method thereof, and a quantum dot light-emitting diode. The composite material includes an organic semiconductor material and an organic substance with a polyphenyl ring structure dispersed in the organic semiconductor material, and a polar functional group is connected to the polyphenyl ring structure of the organic substance. The composite material uses the organic compound with a polyphenyl ring structure to modify the organic semiconductor material, which effectively solves the problem that the quantum dot surface and the organic semiconductor material have an excessive hole injection barrier, low hole mobility, and easy charge accumulation at the QD/HTL interface. And the problem of device charge imbalance, which can improve the life and efficiency of the device. |
