TECHNOLOGY FOCUS - ELECTRONICS - Preferred Layer: The light-emitting layer contains the aromatic-amine derivative (0.1-20 wt.%).    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation: No general preparation given. Preferred Definitions:    Ar11-Ar14=phenyl or naphthyl;    A1-A4=1-4C alkyl, or aryl having 6-10 nuclear carbon atoms;    a-d=1 or 2;    B'1=H, 1-4C alkyl, or aryl having 6-10 nuclear carbon atoms;and    z=1-4.    SPECIFIC COMPOUNDS - 32 Aromatic-amine derivatives are disclosed e.g. Nasterisk3asterisk,Nasterisk9asterisk-bis-(3,5-dimethyl-phenyl)-Nasterisk3asterisk,Nasterisk9asterisk-bis-(4-isopropyl-phenyl)-phenanthrene-3,9-diamine of formula (A), Nasterisk3asterisk,Nasterisk9asterisk-bis-(4-cyclohexyl-phenyl)-10-methyl-Nasterisk3asterisk,Nasterisk9asterisk-diphenyl-phenanthrene-3,9-diamine, Nasterisk3asterisk,Nasterisk9asterisk-bis-biphenyl-3-yl-Nasterisk3asterisk,Nasterisk9asterisk-diphenyl-phenanthrene-3,9-diamine, 6,Nasterisk3asterisk,Nasterisk3asterisk,Nasterisk9asterisk,Nasterisk9asterisk-pentaphenyl-phenanthrene-3,9-diamine, Nasterisk3asterisk,Nasterisk9asterisk-di-naphthalen-2-yl-Nasterisk3asterisk,Nasterisk9asterisk-di-m-tolyl-phenanthrene-3,9-diamine.    EXAMPLE - (In g) 9-dibromophenanthrene (5), N-(3,5-dimethylphenyl)-N-(4-isopropylphenyl)amine (8.6), tris(dibenzylidene acetone)dipalladium (273 mg), tri-t-butylphosphine (241 mg), t-butoxy sodium (4.3), and toluene (40 mL) were stirred at 80 degrees C for 8 hours. The reaction mixture was returned to room temperature and filtered. The obtained solution was purified using hexane/toluene, and the solid was recrystallized using toluene/ethanol, and dried to obtain Nasterisk3asterisk,Nasterisk9asterisk-bis-(3,5-dimethyl-phenyl)-Nasterisk3asterisk,Nasterisk9asterisk-bis-(4-isopropyl-phenyl)-phenanthrene-3,9-diamine (4.4) of formula (A), as a yellow-white solid. An organic electroluminescent element obtained using the compound emitted blue light with a maximum wavelength of 457 nm, with a luminous efficiency of 6.4 cd/A and a light-emitting luminance of 64 cd/m2.
