The invention discloses a doped dark blue organic luminescent material and its preparation method and application. The doped dark blue organic luminescent material includes a host material and a guest material. The molecular structure formula of the host material is as follows: where R1 and R2 are with One of them; wherein, R1 and R2 are connected to anthracene through its 1 , 2 , 3 or 4 position; the molecular structure formula of the guest material is as follows: Among them, R3 and R4 are One of them; wherein, R 3 and R 4 pass their 1, 2, 3 or 4 positions with connect. The preparation method of the present invention is simple in process, and the prepared doped dark blue organic luminescent material has good thermal stability, high purity, high quantum efficiency and good stability, which solves the difficulty in the performance of devices prepared by existing blue light fluorescent materials.
