A class of electroluminescent materials of pyrene derivatives and their preparation methods and applications |
| abstract |
The invention discloses a class of electroluminescent materials of pyrene derivatives and a preparation method and application thereof. The pyrene derivative has a seven-membered condensed ring structure, and the better planarity is beneficial to the injection and transport of carriers and improves the optoelectronic properties of the material; The thermal resistance of the material meets the practical needs of the material. In the present invention, the electroluminescent material of a class of pyrene derivatives is obtained by C-C coupling reaction or C-N coupling reaction, and can be prepared by solution processing techniques such as spin coating, inkjet printing or printing film formation. The light-emitting layer of a light-emitting diode. |
