| abstract |
The present invention relates to an organic electroluminescent material with pyrroloindole as the core and its application, which has a molecular structure as shown in the following formula: Wherein, R 1 -R 8 are the same and represent an H atom or a methyl group, and Ar 1 and Ar 2 independently represent one of an aromatic substituent and a nitrogen-containing heterocyclic substituent. The organic electroluminescent material with bispyrroloindole as the core provided by the present invention has appropriate molecular weight, good film stability, and suitable molecular energy level, and can be used as a light-emitting layer of an OLED device and applied to organic electroluminescence in the field. |
