Abstract
The present disclosure relates to an organometallic compound, an organic light-emitting device including the same, and a diagnostic composition including the organometallic compound, wherein the organometallic compound is represented by Formula 1: is suitable for use in an organic layer of an organic light-emitting device. The organic light-emitting device may have, due to the inclusion of an organic layer including the organometallic compound represented by Formula 1, a low driving voltage high efficiency, high power, high quantum efficiency, a long lifespan, a low roll-off ration, and excellent color purity. In addition, the organometallic compound represented by Formula 1 may provide high luminescent efficiency. Accordingly, a diagnostic composition including the organometallic compound may have high diagnostic efficiency. In Formula 1, groups and variables are the same as described in the specification.
