Organic electroluminescence element
摘要:
An organic EL device which contains an anode, a cathode, and at least one organic thin-film layer including a light emitting layer which contains a compound represented by the following general formula (1): wherein Ar1, Ar2 represent a substituted or unsubstituted aromatic hydrocarbon group, or a substituted or unsubstituted aromatic heterocyclic group; Y represents a single bond or —CH═CH— group; R1 to R4 represent each independently a hydrogen, a halogen, a cyano group, a substituted amino group, a substituted alkoxy group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aromatic hydrocarbon group, or a substituted or unsubstituted aromatic heterocyclic group; any two of R1 to R4 may form a ring; R5 represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted aromatic hydrocarbon group, or a substituted or unsubstituted aromatic heterocyclic group.
