Paragraph 0117-0119, (2020/06/16)
The invention provides a material for an organic light-emitting device and the organic light-emitting device thereof, and relates to the technical field of organic photoelectric materials. According to the invention, C site substitution of carbazole is carried out with an aryl-substituted pyrimidinyl, and N site substitution of carbazole is carried out with a specific heteroaryl; finally, the dendritic-structure material for the organic light-emitting device is formed. The glass transition temperature is high, the thermal stability is good, the film-forming property is good, the refractive index is high, the water and oxygen corrosion resistance is realized, and the synthesis is simple; the material can be applied to the organic light-emitting device as a covering layer, can effectively solve the problems of low refractive index, poor thermal stability, poor water and oxygen resistance stability, low luminous efficiency and short service life of the organic light-emitting device, and the organic light-emitting device has the advantages of high luminous efficiency and long service life.
