Abstract:
Provided are an organometallic compound, an organic light-emitting device including the organometallic compound, and an organic light-emitting apparatus including the organic light-emitting device. The organometallic compound has the structure M(L1)n1(L2)n2, wherein M is a transition metal, L1 is a ligand represented by the following structure:
wherein n1 is 1, 2, or 3, and when n1 is two or more, two or more L1(s) are identical to or different from each other, L2 is an organic ligand, and n2 is 0, 1, or 2, and when n2 is two or more, two or more L2(s) are identical to or different from each other. The sum of n1 and n2 is 2 or 3. More details about Formula 2 is provided in the disclosure.
wherein n1 is 1, 2, or 3, and when n1 is two or more, two or more L1(s) are identical to or different from each other, L2 is an organic ligand, and n2 is 0, 1, or 2, and when n2 is two or more, two or more L2(s) are identical to or different from each other. The sum of n1 and n2 is 2 or 3. More details about Formula 2 is provided in the disclosure.
