Organic electroluminescent device using hole-injectable, light-emitting material |
摘要 |
An organic EL device with high brightness and long lifetime, which is capable of driving at low voltage, is provided. As the material for constituting the organic EL device, a specific styryl amino group-containing diphenyl aminoarylene represented by the following general formula Ä1Ü (wherein Ar1 is a substituted or unsubstituted arylene group having 5-42 carbons, Ar2 to Ar5 each independently represents substituted or unsubstituted C6 to C20 aryl groups, at least one of which is a styrylphenyl group represented by the following general formula Ä2Ü) is used in a light-emitting zone adjacent to an anode. <CHEM> <CHEM> <IMAGE> |
