TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The organic light emitting device has a forward structure in which an anode (2), at least one organic material layer, and a cathode (7) are sequentially laminated on a substrate (1). The organic light emitting device has a reverse structure in which a cathode, at least one organic material layer, and an anode are sequentially laminated on a substrate. The organic light emitting device comprises (I) which is included in the organic material layer comprising hole injecting layer (3), hole transporting layer (4), light emitting layer, electron injecting or electron transporting layer. The organic material layer comprises a light emitting layer comprising (I). The organic material layer comprises an electron transporting layer or electron injecting layer, where the electron transporting layer or the electron injecting layer comprises (I).    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (Disclosed): Preparation (I) comprises: subjecting a halogen-substituted anthraquinone derivative of formula (a1) and a boronic acid compound of formula (R4-B-(OH)2) or boronic ester to Suzuki coupling in the presence of a palladium catalyst to prepare a substituted anthraquinone derivative of formula (a2); preparing a dialcohol derivative of formula (a3) from (a2); and reducing (a3) to give (I).A = Br, Cl or I. SPECIFIC COMPOUNDS - 562 Compounds (I) are disclosed e.g. (9,10-di-naphthalen-2-yl-anthracen-2-yl)-phenyl-pyridin-2-yl-amine, (9,10-diphenyl-anthracen-2-yl)-phenyl-pyridin-2-yl-amine, (9,10-bis-biphenyl-4-yl-anthracen-2-yl)-phenyl-pyridin-2-yl-amine, (9,10-bis-(4-naphthalen-2-yl-phenyl)-anthracen-2-yl)-phenyl-pyridin-2-yl-amine and (9,10-di-naphthalen-2-yl-anthracen-2-yl)-di-pyridin-2-yl-amine of formula (Ia).    EXAMPLE - 2,2'-Dipyridylamine (5 g), 2-bromo-9,10-dinaphthylanthracene (12.3 g), and sodium tertiary butoxide (7 g) were added to toluene (250 ml). The mixture was heated to 50 degrees C. Bis(tri-tert-butyl-phosphine)palladium (61.5 mg) was added and then heated and agitated for 3 hours. The temperature was cooled to normal temperature, celite was added, and the agitation was performed for 10 minutes. The suspension solution was filtered. The filtrate was distilled under reduced pressure and recrystallized with ethanol (200 ml) to obtain (9,10-di-naphthalen-2-yl-anthracen-2-yl)-di-pyridin-2-yl-amine (10.1 g, 70%).
