TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The organic electronic device comprises an organic compound or organometallic compound with green or blue electroluminescence, in addition to (I). In the organic electronic device, 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 one or both electrode(s) among the pair of electrodes.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (Disclosed): Preparation of (I) comprises: mixing iridium trichloride and subsidiary ligand compound of formula (L-H) in a solvent (e.g. 2-ethoxyethanol) at a molar ratio of 1:2-3, and heating the mixture under reflux, and then isolating to obtain the diiridium dimer complex of formula (V); and heating (V) with substituted quinoline compounds of formula (VI) in organic solvent to give organic phosphorescent iridium complex compounds of formula (VII) (representative of (I)) (where n is 1). Preferred Components: The organic layer comprises compound(s) comprising arylamine compounds or styryl arylamine compounds, or metal(s) comprising organometals of group 1, group 2, 4th period and 5th period transition metals, lanthanide metals or d-transition elements in the periodic table of elements. The organic layer comprises an electroluminescent layer and a charge generating layer. SPECIFIC COMPOUNDS - 2060 Compounds (I) are disclosed e.g. iridium complex of 3-naphthalen-1-yl-benzo(f)quinoline compound of formula (Ia), iridium complex of 2-phenyl-benzo(h)quinoline compound of formula (Ib), iridium complex of 2-phenyl-benzo(h)quinoline compound of formula (Ic), iridium complex of 2,4-diphenyl-benzo(h)quinoline compound of formula (Id) and iridium complex of 4-(4-fluoro-phenyl)-2-phenyl-benzo(h)quinoline compound of formula (Ie).    EXAMPLE - 2-Aminonaphthalen-1-aldehyde (5 g), 1-acetonaphthalene (4.1 ml), potassium hydroxide (3.3 g) and ethanol (100 ml) were charged in a vessel, and the mixture was stirred under reflux in the presence of argon atmosphere. When the reaction was completed, the reaction mixture was cooled to room temperature, and an excess amount of aqueous ammonium hydroxide solution was added to it and worked up to give 3-naphthalen-1-yl-benzo(f)quinoline (XX) (4.8 g, 64%). (XX) (4 g) and iridium chloride (2.1 g) were dissolved in 2-ethoxyethanol (38 ml) and distilled water (13 ml), and the solution was stirred under reflux in the presence of argon atmosphere for 24 hours and worked up to give iridium dimer complex of 3-naphthalen-1-yl-benzo(f)quinoline compound of formula (YY) (8.9 g, 85%). (YY) (8 g), 2,4-pentanedione (1.7 ml) and sodium carbonate (3.5 g) were dissolved in 2-ethoxyethanol (100 ml), and the solution was heated for 4 hours and worked up to give iridium complex of 3-naphthalen-1-yl-benzo(f)quinoline compound (Ia) (1.5 g, 35%).
