A blue light-emitting material which is excellent in color purity and fluorescence quantum yield of a luminescent color, can form a stable amorphous film, can be easily synthesized in a high yield with a short reaction route, and a method for producing the same And a high-brightness organic electroluminescent device using the same. An organic electroluminescent device using a 9,10-bis (5,6,7,8-tetrahydro-2-naphthyl) anthracene compound represented by the general formula [I] and a luminescent material thereof. This compound is produced by synthesizing an aryl boronic acid or an ester thereof from a 5,6,7,8-tetrahydro-2-naphthol compound and reacting it with a 9,10-dihaloanthracene compound. [However, R 1 , R 2 , R 3 and R 4 are each independently a hydrogen atom, a fluorine atom, a trifluoromethyl group, a cyano group, or a substituted or unsubstituted alkyl group, an alkoxy group, an aryl group. Or an aryloxy group or the like. ] [Selection figure] None |
