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. 본 발명은 하기 일반식(I)의 이-치환된(bis-substituted) 퀴놀린계 오렌지색 또는 적색 형광물질, 이의 제조방법 및 이를 발광층에 포함하는 유기전기발광소자에 관한 것으로, 본 발명에 따른 형광 물질은 안정성이 우수하고, 이를 발광층에 포함하는 유기전기발광소자는 발광 색상이 오렌지색에서 적색 영역까지 발현될 수 있다: 상기 식에서, A는 C알킬렌, 또는 C알킬 또는 C알콕시로 치환되거나 치환되지 않은 아릴, 아릴옥시 또는 헤테로아릴이고, R내지 R는 각각 독립적으로 수소, C알킬, C알콕시, 또는 C알킬 또는 C알콕시로 치환되거나 치환되지 않은 아릴, 아릴옥시 또는 헤테로아릴이다.
