| titleOfInvention | A kind of preparation method of asymmetric electron donor substituted carborane light-emitting material and OLED device |
| abstract | The invention belongs to the technical field of light-emitting materials, and particularly relates to a preparation method of an asymmetric electron-donor-substituted carborane light-emitting material and an OLED device. In the present invention, an asymmetric alkyne precursor is generated through Sonogashira coupling between 4-bromophenylacetylene and iodocarbazole under the action of a palladium/copper catalyst, then a carborane precursor is generated through a boron cluster addition reaction, and finally a C- N-coupling reaction connects new electron donors to prepare asymmetric electron-donor-substituted carborane light-emitting materials. The boron cluster addition reaction of the preparation method of the present invention can realize the preparation of more than gram level with a moderate yield of about 50%, and the electron donor can be extended to compounds with strong nucleophilicity such as oxygen or sulfur. The preparation method has better practicability and universality. |
