Abstract:
An organic electroluminescent (EL) device comprising an anode, a cathode, and one or more organic thin film layers including a luminescent layer disposed between said anode and said cathode, at least one of said layers containing, in a form of a mixture or a single substance, a dibenzoperylene compound expressed in Formula (4): wherein each of R1 to R16 independently represents a hydrogen atom, a halogen atom, a hydroxy group, a substituted or non-substituted amino group, nitro group or cyano group, a substituted or non-substituted alkyl group, a substituted or non-substituted alkenyl group, a substituted or non-substituted cycloalkyl group, a substituted or non-substituted alkoxyl group, a substituted or non-substituted aromatic hydrocarbon group, a substituted or non-substituted aromatic heterocyclic group, a substituted or non-substituted aralkyl group, a substituted or non-substituted aryloxy group; a substituted or non-substituted alkoxycarbonyl group, or a carboxyl group, and one or more pairs of substituents R1 to R16 may form a ring between two of them, provided R8 and R9 do not form a ring with each other, further wherein at least one of substituents R1 to R16 in Formula (4) represents a diarylamino group expressed by â€”NAr1Ar2, and each of Ar1 and Ar2 independently represents an aryl group having 6 to 20 carbons which may have one or more substituents, wherein the device has, as said organic thin film layer, at least a luminescent layer which includes the compound expressed in Formula (4) in a form of a mixture or a single substance, wherein at least one of substituents R1 to R16 in Formula (4) represents a diarylamino group expressed by â€”NAr1Ar2, and each of Ar1 and Ar2 independently represents an aryl group having 6 to 20 carbons which may have one or more substituents.
