Preferred Component: The organic layer further comprises arylamine compounds or styrylarylamine compounds; and one or more metal(s) selected from organic metals of Group 1, Group 2, fourth period and fifth period transition metals, lanthanide metals, or d-transition elements from the Periodic Table of Elements. The organic layer also comprises a charge generating layer as well as the electroluminescent 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 one or both electrode(s) among the pair of electrodes. The compound has electroluminescent peak with wavelength of not less than 500 nm or not less than 560 nm. SPECIFIC COMPOUNDS - 1089 Compounds (I) are disclosed, e.g. compounds of formulae (Ia)-(Ie).    EXAMPLE - In dry tetrahydrofuran (THF, 500 mL), 2-bromonaphthalene (44.1 g) was dissolved, and 2.5 M n-butyllithium solution in h-hexane (130 mL) was slowly added dropwise at - 78 degrees C. After stirring for 1 hour, 2,6-dibromoanthracene-9,10-dione (30 g) was added, and the resultant mixture was stirred while slowly warming it to room temperature. After 17 hours, water was added, and the mixture was stirred for 30 minutes and extracted with ethyl acetate (500 mL). The extract was washed with water (500 mL), and dried over magnesium sulfate. Distillation of the organic layer under reduced pressure and drying gave 2,6-dibromo-9,10-dihydroxyanthracene-9,10-naphthalene (A) (21.3 g). Then, compound (A) (7 g), potassium iodide (9.64 g) and sodium phosphate monohydrate (9.24 g) were dissolved in acetic acid (150 mL), and the solution was stirred under reflux for 14 hours. The reaction mixture was cooled to 25 degrees C. The mixture was washed with water (400 mL), and extracted with dichloromethane solvent (300 mL). The extract was dried over magnesium sulfate and filtered. After removing the solvent under reduced pressure, the obtained residue was purified via methylene chloride/hexane (1/100) to obtain 2,6-dibromoanthracene-9,10-naphthalene (B) (4.49 g). Then, in a reaction vessel, compound (B) (4 g), iminodibenzyl (3.3 g), palladium(II) acetate (0.07 g), tri-tert-butylphosphine (50% in toluene, 0.3 ml), cesium carbonate (6.6 g), and toluene (50 mL) were stirred at 110 degrees C for 5 hours. After adding methanol (50 ml), the solid produced was filtered under reduced pressure, and washed with distilled water, methanol and hexane. The solid was mixed with ethyl acetate (100 mL), and stirred under reflux for 2 hours. After filtering under reduced pressure, the solid was purified via column chromatography. The solid obtained was dissolved in THF, and the mixture was added to methanol. Filtration under reduced pressure gave Compound (1479) (1.6 g).
