The present invention belongs to the field of organic photoelectric materials, and in particular relates to a dioxphenoxathine derivative and its preparation method and application. The dioxphenoxathine derivative is based on dioxphenoxathil, and its structural formula is as follows: Among them, Ar represents Or ‑R, the Ar1 is phenyl, biphenyl, terphenyl, naphthyl, anthracenyl or phenanthryl; It has the characteristics of good film-forming properties. When the compound of the invention is used as a light-emitting layer material of an OLED light-emitting device, the produced OLED device has good photoelectric properties. |
