| titleOfInvention | Tetraphenylpyrazine compounds, polymers and electroluminescent devices |
| abstract | The invention relates to a tetraphenylpyrazine compound, a polymer and an electroluminescent device. The tetraphenylpyrazine compound has the structure shown in formula (I‑1). The compound structure contains a cross-linking segment, which endows the material with cross-linking and curing properties; and a tetraphenylpyrazine segment. Pyrazine itself is an electron-withdrawing group, which is conducive to electron transmission. In addition, its molecular twist is very large, and it has a large The characteristics of the volume increase the distance between the molecules of the electron transport layer and the molecules of the light-emitting layer, suppress the quenching of excitons to improve the efficiency and stability of the device, and the classic electron-withdrawing structure, which can ensure the performance of electron transport. The combination of the three structures can obtain a crosslinkable electron transport material with good performance. The electron transport material is used for solution processing, can be cross-linked and cured to obtain high thermal stability, and has good electron transport performance, which can reduce the manufacturing cost of OLED and improve the freedom of preparation process. |
