Abstract: Disclosed is a novel organometallic compound represented by a following Chemical Formula 1. The organometallic compound acts as a dopant of a light-emitting layer of an organic light-emitting diode. Thus, an operation voltage of the diode is lowered, and luminous efficiency and a lifespan thereof are improved:

Abstract: An organometallic compound represented by Chemical Formula I, and an organic light-emitting diode containing the same. In the Chemical Formula I, M may represent a central coordination metal, and includes one selected from a the group consisting of molybdenum (Mo), tungsten (W), rhenium (Re), ruthenium (Ru), osmium (Os), rhodium (Rh), iridium (Ir), palladium (Pd), platinum (Pt), and gold (Au). Each of R1 to R8 may independently represent one selected from the group consisting of hydrogen, deuterium, a substituted or unsubstituted C1 to C20 alkyl group, and a substituted or unsubstituted C3 to C20 bicycloalkyl group. A may represent a ring structure of isoquinoline. Each of X1 to X4 may independently represent one selected from CR11 and nitrogen (N).

Abstract: A novel organometallic compound represented by a following Chemical Formula I is described:
wherein R represents a fused ring connected to X1 and X2, with variables as defined herein. The organometallic compound acts as a dopant of a light-emitting layer of an organic light-emitting diode. An organic light emitting device includes the organic light emitting diode and can be a display device or a lighting device. Improved color gamut of the diode, luminous efficiency and a lifespan thereof are achieved, as well as a lower operation voltage of the diode.
