The invention discloses a benzimidazole-containing compound and an application of the benzimidazole-containing compound on an organic electroluminescent device. The compound takes benzimidazole ring as a core, and has the characteristics of difficult crystallization among molecules, difficult aggregation and good film forming ability. When the compound is taken as a luminescent layer main material of an organic light emitting diode (OLED) luminescent device for usage, current efficiency, power efficiency and external quantum efficiency of the device are greatly improved; at the same time, the device life can be obviously increased.
