The invention discloses an arylphenanthraquinone organic light-emitting material, a preparation method and application thereof. The organic light-emitting material takes arylphenanthraquinone as the mother nucleus, and the structural formula is shown as the specification. In the arylphenanthraquinone organic light-emitting material provided by the invention, HOMO and LUMO energy level electron clouds can be effectively separated, thus realizing small S1-T1 state energy gap, effectively improving the exciton utilization rate and high fluorescence radiation efficiency, lowering the efficiency roll-off under high electric current density, and being conducive to reducing device voltage and improving device performance. The arylphenanthraquinone organic light-emitting material provided by the invention can be applied to OLED (organic light emission diodes) device making, and can greatly improve the current efficiency, power efficiency and external quantum efficiency of the device. The arylphenanthraquinone organic
