Design and prepare a luminescent metal iridium complex (or hybrid iridium complex), the structure of which is shown in the following general formula (1): Using the well-developed indolocarbazole series as the structural unit of the organometallic iridium light-emitting ligand not only increases the charge transport ability of the conjugated iridium complex, but also helps to improve the performance of OLED devices, and at the same time increases the light-emitting iridium complex. The solubility of the compound and the reduction of the sublimation temperature make many original light-emitting iridium complexes that are insoluble and difficult to sublime and purify become easily soluble, easy to sublime, and easy to prepare OLED devices by large-scale evaporation. |
