PURPOSE: Provided are a bis-substituted quinoline red phosphor, which is excellent in stability and can express orange to red, and a preparation thereof and an organic electroluminescent element containing the bis-substituted quinoline red phosphor. CONSTITUTION: The bis-substituted quinoline red phosphor is represented by the formula (I) and produced by heat-reacting a compound represented by the formula (II) and a pyran derivative represented by the formula (III) in the molar ratio of about 1:2 in the presence of a base in an alcohol solvent, wherein A is C1-C4 alkylene, or C1-C4 alkyl or C1-C4 alkoxy substituted or unsubstituted aryl, aryloxy or heteroaryl, R1-R12 are independently hydrogen, C1-C4 alkyl, C1-C4 alkoxy, or C1-C4 alkyl or C1-C4 alkoxy substituted or unsubstituted aryl, aryloxy, or heteroaryl. And the organic electroluminescent element has an organic luminescent layer containing the red phosphor. |
