| titleOfInvention | A kind of benzimidazole compound, its synthesis and its application in OLEDs |
| abstract | The invention discloses a benzimidazole compound, its synthesis and its application in OLEDs. The compound is prepared by the following steps: 2-phenylbenzimidazole, 2,4,6-trifluorobenzonitrile, base, adding to an organic solvent, reflux reaction under nitrogen atmosphere for 5-12 h, and then ethanol recrystallization or column chromatography The compound was obtained after separation and purification. In the compound i TPBI-CN containing benzimidazole units of the present invention, the benzimidazole units and benzonitrile units are connected in the form of C-N, while the traditional method requires the addition of expensive noble metal catalysts to form carbon-nitrogen bonds. In addition, there is still a lot of room for improvement in device performance when iTPBI ‑CN is used as an electron transport layer material in organic electroluminescent devices. |
