Pterene modified pyridazine platinum complex phosphorescent material and its preparation method and application |
| abstract |
The invention discloses a pterene-modified pyridazine platinum complex phosphorescent material, a preparation method and an application thereof. The pterene-based modified pyridazine platinum complex can be obtained by modifying the aromatic ring on the main ligand, and its general structural formula is represented by the following formula. The phosphorescent platinum complex of the present invention improves the color purity and luminous efficiency of the phosphorescent material of the platinum complex to the greatest extent by introducing a rigid non-conjugated pterene structure covering the platinum core on the ligand. The preparation method and the obtained pterene-modified pyridazine platinum complex have high internal and external quantum yields, luminous brightness and stability. The electroluminescence device of the present invention, the light-emitting layer of which is prepared by spin-coating film-forming method, has low cost, simple operation, stable chemical property, high luminous brightness and high efficiency, and helps to realize high-efficiency electroluminescence device. |
