Patent ID: 7939669

Claim:
A metallic compound represented by the following Chemical Formula 1: Wherein, M is a transition metal 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 is S, O, or Se, of the Chemical Formula 1 is represented by the following Chemical Formula 2: wherein, in the above Chemical Formulae 2, * denotes a portion that is covalently bound with adjacent aromatic portion, the transition metal M forms a complex while bound with a portion denoted as “a” in the above Chemical Formulae 2 by a covalent bond and bound with X of the Chemical Formula 1 by a coordination bond, R 1 -R 3 , and R 5 -R 14 are hydrogen, a C1 to C20 alkyl, an aryl, a cycloalkyl, a halogen, a linear or branched substituent including at least one halogen, a linear or branched substituent including at least one heteroatom, carbonyl, vinyl, or acetylenyl, or form a cycle, and are the same or different, R 4 is hydrogen, a C1 to C20 alkyl excluding an aromatic cyclic substituent, a cycloalkyl, a halogen, a linear or branched substituent including at least one halogen, or a linear or branched substituent including at least one heteroatom, and L 2 of the Chemical Formula 1 is represented by the following Chemical Formula 4: wherein Z and W in the above Chemical Formula 4 are the same or different and a heteroatom of O, N, S, or P, and R 21 -R 25 in the Chemical Formula 4 are the same or different, and are selected from hydrogen, a C1 to C20 alkyl, an aryl, a cycloalkyl, a halogen, a linear or branched substituent including at least one halogen, a linear or branched substituent including at least one heteroatom, carbonyl, vinyl, or acetylenyl, or form a cycle.
