Patent ID: 7968715

Claim:
A metallic compound represented by the following Chemical Formula 1: wherein M is selected from Ir, Pt, Rh, Re, and Os, m is 2 or 3, n is 0 or 1, the sum of m and n is 3, provided that the sum of m and n is 2 when M is Pt, X is N or P, Y and Q are selected from S, O, or Se, R 1 is one of hydrogen, a C1 to C20 alkyl, a cycloalkyl, a halogen, the alkyl having at least one halogen, or at least one heteroatom substituent, each of R 2 , R 3 , and R 4 is one of hydrogen, a C1 to C20 alkyl, an aryl, a cycloalkyl, a halogen, the alkyl having at least one halogen or at least one heteroatom substituent, carbonyl, vinyl, and acetyleny, and L 2 is represented by the following Chemical Formulae 3, 4, and 5: wherein, in the above formula 3, M forms a complex compound by a covalent bond with a portion denoted as *, and a coordination bond with an adjacent N or P atom, Z and W in the above Chemical Formulae 4 and 5 are the same or different and heteroatoms of O, N, S, or P, and each of R 11 -R 24 in the Chemical Formulae 3, 4, and 5 is one of hydrogen, a C1 to C20 alkyl, an aryl, a cycloalkyl, a halogen, the alkyl having at least one halogen or at least one heteroatom substituent, carbonyl, vinyl, and acetylenyl.
