摘要:
A red phosphorescent composition includes a host material being capable of transporting an electron or a hole; and a dopant material represented by the following Formula 1: wherein each of R1 to R4 is selected from the group consisting of hydrogen atom (H), C1 to C6 alkyl and C1 to C6 alkoxy, and at least one of R1 to R4 is C1 to C6 alkyl, and wherein each of R5 to R7 is selected from the group consisting of hydrogen, C1 to C6 alkyl and halogen atom, and at least one of R5 to R7 is halogen atom, and wherein each of X and Y is selected from the group consisting of H, non-substituted C1 to C6 alkyl and C1 to C6 alkyl substituted by fluorine.
