Abstract
Compounds for organic EL devices which emit light of red, have a high light emission brightness and have a long lifetime of light emission, and organic EL devices using the above compounds, the light-emitting materials being compounds of the formula [1], wherein each of Ar3 to Ar10 is independently a substituted or non-substituted aromatic monocyclic group, a substituted or non-substituted fused polycyclic group or a substituted or non-substituted aromatic heterocyclic group, provided that Ar3 and Ar4 may integrally bond to each other, that Ar5 and Ar6 may integrally bond to each other, that Ar7 and Ar8 may integrally bond to each other, and that Ar9 and Ar10 may integrally bond to each other.
Claims8
A compound for a red light-emitting material for an organic electroluminescence device, which is a compound of the formula (1) and in which the maximum light emission wavelength is in a red light emission region:
- wherein each of Ar3 to A10 is independently a substituted or non-substituted aromatic monocyclic group, a substituted or non-substituted fused polycyclic group or a substituted or non-substituted aromatic heterocyclic group, provided that Ar3 and Ar4 may integrally bond to each other, that Ar5 and Ar6 may integrally bond to each other, that Ar7 and Ar8 may integrally bond to each other, that Ar9 and Ar10 may integrally bond to each other and each of R8 to R15 is independently a hydrogen atom of di(4-methylphenyl)amino.
