The invention provides an organic electroluminescence material containing a phenanthrene structure and an organic light-emitting device thereof, belonging to the technical field of organic photoelectric materials. An organic electroluminescent material containing a phenanthrene structure provided by the present invention contains a phenanthrene ring structure. The phenanthrene ring structure is a blue-light structure with excellent performance and has a higher triplet energy level and a wider energy gap. By connecting the benzimidazole group, the electron transport ability of the blue light host structure is increased, so that the carrier transport is balanced. Compared with the prior art, when it is applied to an organic light-emitting device, especially as a blue light-emitting material in the light-emitting layer, it has relatively high luminous efficiency and low driving voltage. |
