Abstract
Official abstract text for this publication.
An organometallic compound represented by Formula 1: M1(Ln1)n1(Ln2)3-n1 Formula 1 wherein M1 is a first-row transition metal of the Periodic Table of Elements, a second-row transition metal of the Periodic Table of Elements, or a third-row transition metal of the Periodic Table of Elements, Ln1 is a bidentate ligand, n1 is 0, 1, or 2, and Ln2 is a ligand represented by Formula 1A: wherein A1, A2, Y1, Y2, R1 to R3, R10, R20, b10, and b20 are as provided herein, and* and *′ each indicate a binding site to a neighboring atom.
First claim
Opening claim text (preview).
What is claimed is: 1 . A compound represented by one of Compounds 1 to 36: 2 . An organic light-emitting device comprising: a first electrode; a second electrode, and an organic layer arranged between the first electrode and the second electrode and comprising an emission layer, wherein wherein the organic layer comprises at least one organometallic compound of claim 1 . 3 . The organic light-emitting device of claim 2 , wherein the emission layer comprises the at least one organometallic compound. 4 . The organic light-emitting device of claim 3 , wherein the emission layer further comprises a host, and an amount of the host is greater than an amount of the at least one organometallic compound in the emission layer. 5 . The organic light-emitting device of claim 4 , wherein the emission layer emits green light having a maximum emission wavelength of about 500 nanometers to about 600 nanometers. 6 . The organic light-emitting device of claim 2 , wherein the first electrode is an anode, the second electrode is a cathode, the organic layer further comprises a hole transport region between the first electrode and the emission layer and an electron transport region between the emission layer and the second electrode, the hole transport region comprises a hole injection layer, a hole transport layer, an electron blocking layer, a buffer layer, or a combination thereof, and the electron transport region comprises a hole blocking layer, an electron transport layer, an electron injection layer, or a combination thereof. 7 . An electronic apparatus comprising the organic light-emitting device of claim 2 .
