TECHNOLOGY FOCUS - ELECTRONICS - Preferred Arrangement: The organic thin film layer has positive hole transport layers. The aromatic-amine derivative is contained in the layer which touches the light-emitting layer directly. The organic thin film layer has positive hole injection layers. The aromatic-amine derivative is contained in the layer which touches the anode directly. The positive hole transport layer and/or positive hole injection layer contain an acceptor material.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (disclosed): The new aromatic-amine derivative is obtained by reacting a halogen intermediate compound of formula: Ar1-X and an amine intermediate compound of formula: Ar2Ar3NH in the presence of a catalyst (e.g. tris(dibenzylidene acetone)dipalladium(0)) and a base (e.g. t-butoxy sodium).X=halo.Preferred Composition: The light-emitting layer contains a styrylamine compound and/or an arylamine compound. SPECIFIC COMPOUNDS - 129 Aromatic-amine derivatives are disclosed e.g. (9,9-dimethyl-7-naphthalen-2-yl-9H -fluoren-2-yl)-bis-(1,1';4',1")terphenyl-4-yl-amine of formula (IA), (9,9-dimethyl-7-phenanthren-9-yl-9H-fluoren-2-yl)-bis-(1,1';4',1")terphenyl-4-yl -amine, (9,9-dimethyl-7-naphthalen-2-yl-9H-fluoren-2-yl)-bis-(9,9-dimethyl-7-phenyl-9H -fluoren-2-yl)-amine, bis-biphenyl-4-yl-(9,9-dimethyl-7-naphthalen-2-yl-9H-fluoren-2-yl)-amine, and bis-biphenyl-4-yl-(9,9-dimethyl-7-(4-naphthalen-2-yl-phenyl)-9H-fluoren-2-yl)-amine.    EXAMPLE - (In g) (1,1';4',1")terphenyl-4-yl-(1,1';4',1")terphenyl-4"-yl-amine (9.4), 9,9-dimethyl-2-naphthalen-2-yl-9H-fluorene (8), t-butoxy sodium (2.6), tris(dibenzylidene acetone)dipalladium(0) (92 mg), tri-t-butylphosphine (42 mg), and dehydrated toluene (100 mL) were reacted at 80 degrees C for 8 hours. Water (500 mL) was added after cooling. The mixture was filtered, and the filtrate was extracted with toluene and dried. The crude product obtained by concentrating under reduced pressure was recrystallized and dried to obtain (9,9-dimethyl-7-naphthalen-2-yl-9H -fluoren-2-yl)-bis-(1,1';4',1")terphenyl-4-yl-amine (8.6) of formula (IA), as pale yellow powder. An organic electroluminescent element obtained using the compound had an initial luminance of 5000 cd/m2, a luminous efficiency of 5.5 cd/A, and a light-emission half life of 460 hours.
