Abstract: Disclosed is a novel organometallic compound in which a main ligand (LA) has a fused ring structure including a thiophene group. The organometallic compound acts as a dopant of a phosphorescent 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: The present disclosure relates to an organic light emitting diode that comprises an organic compound in which a carbazole moiety fused with an aromatic ring and a hetero aromatic ring is linked to a triazine moiety substituted with aromatic and/or hetero aromatic groups via an aromatic linker, and at least one protium constituting the aromatic and/or hetero aromatic groups of the triazine moiety and the aromatic linker moiety is substituted with deuterium, and an organic light emitting device including the diode. The molecular conformation of the deuterium-substituted triazine moiety and the aromatic linker moiety is not deteriorated and dissolved, and therefore, the organic compound can implement luminous efficiency and luminous lifetime as an organic compound in which whole protiums are substituted with deuteriums.
