  • ORGANIC ELECTROLUMINESCENT DOPANT MATERIAL AND LIGHT-EMITTING DEVICE
    Publication number: 20260190848
    Abstract: The present invention provides an organic electroluminescent dopant material and a light-emitting device. By introducing a deuterium atom group at a specific position on a thiophene ring and adjusting the molecular spacing and bond energy of the obtained compound, a dopant material having a specific atomic structure is obtained. After the obtained organic compound having a specific atomic structure is used in the organic electroluminescent device, the driving voltage is reduced, and the luminous efficiency of the device is improved.
