wherein, M is selected from Ir, Pt, Rh, Re, or Os, m is 2, provided that m is 1 when M is Pt,

 of the Chemical Formula 1 is represented by the following Chemical Formulae 2:

wherein, a portion denoted as * in the above Chemical Formulae 2 has a carboxyl substituent, and transition metal M forms a complex compound by a covalent bond with the carboxyl group and a coordination bond with an adjacent N or P atom, and
R1-R4 are the same or different, and are hydrogen, a C1 to C20 alkyl excluding an aromatic cyclic substituent, a cycloalkyl, or a halogen, and
L1 is represented by the following formula 3:

wherein, L1 in the above formula 3 is a independent ligand having a covalent bond site with a carbon denoted as * and a coordination bond with nitrogen and forming a complex compound with the transition metal M of the Formula 1,
X is a hetero atom of nitrogen, oxygen, sulfur, or phosphorus, and
Z1 and Z2 are atoms for forming a C4 to C7 aromatic hydrocarbon ring or aromatic heterocyclic ring and represented by any one of the following Chemical Formulae 5:

2. An organic electroluminescence device comprising the compound represented by the following Chemical Formula 1:

wherein, M is selected from Ir, Pt, Rh, Re, or Os, m is 2, provided that m is 1 when M is Pt,
