Summary:The present invention relates to an organic compound in which a (sila)acridine moiety, serving as an electron donor, is connected by a linker to a triazine moiety serving as an electron acceptor; and a spiro aromatic moiety is connected to a (sila)acridine moiety. Due to containing both electron donor and electron acceptor moieties in one molecule, charges can migrate easily within the molecule, and thus the luminous efficiency may be improved. In addition, as the (sila)acridine moiety is connected to the spiro aromatic moiety, the three-dimensional structure of the molecule is hindered. Accordingly, the organic compound of the present invention may be used as a delayed-fluorescence dopant emitting blue light. The organic compound of the present invention may be used to realize organic light-emitting devices, such as organic light-emitting diodes, display devices, and lighting devices, that have a low driving voltage and excellent luminous efficiency and chromatic purity. 본 발명은 전자주개로 기능하는 (실라)아크리딘 모이어티에 전자받개인 트리아진 모이어티가 링커를 통하여 연결되며, (실라)아크리딘 모이어티에 스파이로 방향족 모이어티가 연결된 유기 화합물에 관한 것이다. 하나의 분자 내에 전자주개와 전자받개 모이어티를 모두 포함하고 있어, 분자 내에서 전하가 쉽게 이동하여 발광 효율이 향상될 수 있다. 또한, (실라)아크리딘 모이어티는 스파이로 방향족 모이어티로 연결되어 있어, 분자의 3차원 입체구조가 제한된다. 따라서 본 발명의 유기 화합물은 청색을 발광하는 지연 형광 도펀트로 사용될 수 있다. 본 발명의 유기 화합물을 적용하여 구동 전압이 낮으면서, 발광 효율 및 색 순도가 우수한 유기발광다이오드, 표시장치 및 조명 장치와 같은 유기발광장치에 활용될 수 있다.
