    摘要： Disclosed is a purification apparatus and method. The purification apparatus includes: a mobile phase distillation part for distilling a mobile phase; a mobile phase liquefaction part for liquefying the distilled mobile phase; and a purification part disposed between the mobile phase distillation part and the mobile phase liquefaction part, for mixing the mobile phase liquefied at the mobile liquefaction part with to-be-purified material, removing impurities from the mixture through a bonded phase, and sending the impurity-removed purified material to the mobile phase distillation part.

    摘要： Disclosed herein are red phosphorescent compounds of the following Formulas 1 to 3: wherein R1 and R2 are independently a C1-C4 alkyl group, R3, R4, R5 and R6 are independently selected from hydrogen, C1-C4 alkyl groups and C1-C4 alkoxy groups, and is selected from 2,4-pentanedione, 2,2,6,6,-tetramethylheptane-3,5-dione, 1,3-propanedione, 1,3-butanedione, 3,5-heptanedione, 1,1,1-trifluoro-2,4-pentanedione, 1,1,1,5,5,5-hexafluoro-2,4-pentanedione, and 2,2-dimethyl-3,5-hexanedione; wherein R1, R2, R3 and R4 are independently selected from C1-C4 alkyl groups and C1-C4 alkoxy groups, and is selected from 2,4-pentanedione, 2,2,6,6,-tetramethylheptane-3,5-dione, 1,3-propanedione, 1,3-butanedione, 3,5-heptanedione, 1,1,1-trifluoro-2,4-pentanedione, 1,1,1,5,5,5-hexafluoro-2,4-pentanedione and 2,2-dimethyl-3,5-hexanedione; wherein R1, R2, R3 and R4 are independently selected from hydrogen, C1-C4 alkyl groups and C1-C4 alkoxy groups, and is selected from 2,4-pentanedione, 2,2,6,6,-tetramethylheptane-3,5-dione, 1,3-propanedione, 1,3-butanedione, 3,5-heptanedione, 1,1,1-trifluoro-2,4-pentanedione, 1,1,1,5,5,5-hexafluoro-2,4-pentanedione and 2,2-dimethyl-3,5-hexanedione. Further disclosed herein is an organic electroluminescent (EL) device comprising an anode, a hole injecting layer, a hole transport layer, a light-emitting layer, an electron transport layer, an electron injecting layer, and a cathode laminated in this order wherein one of the red phosphorescent compounds is used as a dopant of the light-emitting layer.
