Abstract: |
The invention relates to a new compound and an organic electroluminescent device containing the compound. The structural formula of the compound is shown as below, Ar1 and Ar2 are respectively and independently selected from substituted or unsubstituted aromatic group, aromatic ethylene group, polycyclic aromatic group, polycyclic aromatic ethylene group, aromatic amine group and a polycyclic compound containing nitrogen atoms or a heterocyclic compound containing nitrogen atoms. The invention resolves the problems existing in the colorimetric purity, luminescent efficiency, etc. of the currently used luminescent materials. The material of the invention can be used as a luminescent material, and the electroluminescent device prepared of the material of the invention has the predominant performances of high colorimetric purity, high brightness and high efficiency. |
