First claim
Opening claim text (preview).
What is claimed is: 1 . An organometallic compound selected from the following Compounds: 2 . An organic light-emitting device comprising: a first electrode; a second electrode; and an organic layer between the first electrode and the second electrode and comprising an emission layer, wherein the organic layer comprises at least one of the organometallic compounds of claim 1 . 3 . The organometallic compound 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 any combination thereof, and the electron transport region comprises a hole blocking layer, an electron transport layer, an electron injection layer, or any combination thereof. 4 . The organometallic compound of claim 2 , wherein the emission layer comprises a host and the at least one organometallic compound, and an amount of the host in the emission layer is greater than an amount of the organometallic compound.
