The invention discloses a photoelectric material with homobenzene as the core and application thereof. The photoelectric material has higher triplet energy level, higher glass transition temperature, good film-forming stability and wider energy gap , using it as a hole transport/electron blocking material or a light-emitting layer material in an organic light-emitting device can significantly reduce the voltage and improve the device efficiency. The current efficiency, power efficiency and external quantum efficiency of the device made of the optoelectronic material of the present invention are greatly improved; meanwhile, the lifespan of the device is significantly improved. |
