Provided in the present invention is a phosphorescent compound represented by the chemical formula. Each of R1 to R14 is independently selected from hydrogen, deuterium (D), halogens of F, Cl, and Br, CF3, a cyano group, a C1 to C18 alkyl group of, a C1 to C18 alkoxy group, a substituted or unsubstituted C6 or more aromatic group, a C5 or more substituted or unsubstituted heteroaromatic group, a C1 to C18 amine group, an amine group having a substituted C6 or more aromatic group, an amine group having a substituted C5 or more heteroaromatic group, and a silyl group substituted with a C1 to C18 alkyl group, a C6 or more aromatic group or a C5 or more heteroaromatic group. The phosphorescent compound in the present invention solves a problem of low quantum efficiency of a green phosphorescent compound. |
