TECHNOLOGY FOCUS - ELECTRONICS - Preferred Layer: The organic layer formed using the composition is a light-emitting layer (5). A positive hole transport layer (4) is formed by wet film formation adjacent the light-emitting layer. The positive hole transport layer is formed by crosslinking a crosslinkable compound.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (disclosed): Compound (II) is obtained as compound (I) by halogenating a chrysene ring and coupling with a secondary arylamine of formula: A1-NH-A2(A3-NH-A4).A1-A4=aryl. SPECIFIC COMPOUNDS - 11 Compounds are disclosed e.g. N,N'-bis-biphenyl-4-yl-N,N'-bis-(4-hexyl-phenyl)-chrysene-6,12-diamine of formula (IA), N,N'-bis-biphenyl-4-yl-N,N'-bis-(4-(1-methyl-1-phenyl-ethyl)-phenyl)-chrysene-6,12-diamine, N,N,N',N'-tetrakis-(4'-hexyl-biphenyl-4-yl)-chrysene-6,12-diamine, N,N,N',N'-tetrakis-(4'-hexyl-biphenyl-4-yl)-chrysene-6,12-diamine, 2-fluoro-Nasterisk12asterisk-(3'-fluoro-biphenyl-4-yl)-Nasterisk6asterisk-(3-fluoro-phenyl)-Nasterisk6asterisk,Nasterisk12asterisk-bis-(4'-hexyl-biphenyl-4-yl)-chrysene-6,12-diamine, and N,N'-bis-(3,4-dimethyl-phenyl)-N,N'-bis-(4'-hexyl-biphenyl-4-yl)-chrysene-6,12-diamine.    EXAMPLE - (In g) tri(t-butyl)phosphine (260) was added to dry toluene (10 mL) suspension liquid of palladium acetate (96 mg) in nitrogen atmosphere, and stirred at 60 degrees C for 30 minutes, to obtain a catalyst. In nitrogen atmosphere, hexylamine (4.94), dehydrated toluene (50 mL) suspension of t-butoxy sodium (5), and 4-bromobiphenyl (4.12) were added and stirred. The catalyst was added and stirred for 3 hours. After extraction with toluene, the mixture was washed with water and solvent was distilled off. The residue was recrystallized using ethanol/methylene chloride, to obtain biphenyl-4-yl-(4-hexyl-phenyl)-amine (2.6) with a yield of 37%. Dehydrated toluene (50 mL) suspension liquid of t-butoxy sodium (3.29), the obtained compound (3.76), and 6,12-dibromo-chrysene (2) were stirred in nitrogen atmosphere, and catalyst was added. The mixture was stirred for 6 hours, refluxed, and opened in water. Extraction was carried out with toluene, followed by washing with distilled water, and distillation of solvent. The residue was purified using hexane/methylene chloride, to obtain N,N'-bis-biphenyl-4-yl-N,N'-bis-(4-hexyl-phenyl)-chrysene-6,12-diamine (2.3) with a yield of 50%. The obtained compound had chromaticity value (x,y) of 0.14 and 0.15 and maximum wavelength of 461 nm in emission spectrum, and provided organic electroluminescent element having brightness of 4.6 cd/A.
