The invention belongs to the technical field of organic electroluminescence display, and in particular relates to a polyheterocyclic compound and an application thereof. The polyheterocyclic compound of the present invention has the structure shown in the general formula (I), which has a higher triplet energy level, better carrier mobility, and can match the energy level of the adjacent layer, and has a relatively high energy level. High thermal stability and film-forming stability; can be applied to corresponding red and green phosphorescent OLED devices, which can reduce the driving voltage and improve the luminous efficiency of the device. |
