- Derivative containing triphenylene structure, preparation method thereof, and organic light emitting diode
-
The invention provides a derivative containing a triphenylene structure, a preparation method thereof, and an organic light emitting diode, and belongs to the technical field of organic photo-electricmaterials. The compound has the structure represented as the formula (I). In the invention, hole movement degree is increased by combining the triphenylene and triazine structures, so that the compound has maximized hole transport and light-emitting effects. By structurally regulating the R1, R2, R3 and R4 groups, the light-emitting effect of the compound is further improved. The derivative containing the triphenylene structure is applied to the OLEDs, is high in light-emitting efficiency and is an organic light-emitting material having excellent performance.
