TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Device: The organic layer comprises compound selected from arylamine compounds and styrylarylamine compounds. The organic layer comprises at least one metal selected from organic metals of Group 1, Group 2, 4th period and 5th period transition metals, lanthanide metals and d-transition elements. The organic display comprises an organic electroluminescent compound having the electroluminescent peak with wavelength of not greater than 500 nm, and an organic electroluminescent compound having the electroluminescent peak with wavelength of not less than 560 nm, at the same time. The organic layer comprises an electroluminescent layer and a charge generating layer. A mixed region of reductive dopant and organic substance, or a mixed region of oxidative dopant and organic substance is placed on the inner surface of at least one electrode among the pair of electrodes.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation: No general method for preparation of (I) is given. SPECIFIC COMPOUNDS - 4960 Compounds are disclosed as (I) e.g. 9,10-di-tert-butyl-N,N'-bis-(4-(9,9-dimethyl-9H-fluoren-2-yl)-phenyl)-N,N'-diphenyl-anthracene-2,6-diamine (IA); 9,10-di-tert-butyl-N,N'-bis-(9,9-dimethyl-7-phenyl-9H-fluoren-2-yl)-N,N'-diphenyl-anthracene-2,6-diamine; 9,10-di-tert-butyl-N,N'-bis-(9,9-dimethyl-7-phenyl-9H-fluoren-2-yl)-N,N'-di-naphthalen-2-yl-anthracene-2,6-diamine; 9,10-di-tert-butyl-N,N'-bis-(9,9-dimethyl-7-phenyl-9H-fluoren-2-yl)-N,N'-di-naphthalen-1-yl-anthracene-2,6-diamine; and N,N'-bis-biphenyl-3-yl-9,10-di-tert-butyl-N,N'-bis-(9,9-dimethyl-7-phenyl-9H-fluoren-2-yl)-anthracene-2,6-diamine.    EXAMPLE - 2,6-Dibromo-9,10-di-tert-butyl-anthracene (5 g), 4-(9,9-dimethyl-9H-fluoren-2-yl)-phenyl)-phenyl-amine (12.09 g), palladium acetate (Pd(OAc)) (0.25 g), and cesium carbonate (Cs2CO3) (16.35 g) were added to toluene solvent (100 ml) under nitrogen atmosphere, and the mixture was stirred. Immediately added was tri(tert-butyl)phosphine (0.5 ml), and the resultant mixture was stirred under reflux at 120 degrees C for 6 hours. After cooling, methanol (200 ml) was added, and the mixture was stirred for 1 hour. The solid produced in the reaction vessel was filtered. The solid obtained was dissolved in chloroform solvent (2 l), and filtered. The solvent was evaporated, and the solid obtained was washed to obtain 9,10-di-tert-butyl-N,N'-bis-(4-(9,9-dimethyl-9H-fluoren-2-yl)-phenyl)-N,N'-diphenyl-anthracene-2,6-diamine (5.18 g, 47%) as a greenish solid.
