The present disclosure provides a poly(spirobifluorene) having a structure represented by Formula (I). In the present disclosure, a polymer containing carbazolyl spirobifluorene is synthesized by introducing a carbazolyl group at a side chain of a spirobifluorene. No intramolecular charge transfer from a main chain to a side chain occurs in the carbazolyl spirobifluorene polymer prepared in the present disclosure. And the polymer has a good hole transport capability due to the modification with carbazole, and a good device efficiency can be achieved while retaining the advantage of the color purity of pure blue light. Meanwhile, by introducing an aromatic group to the poly(spirobifluorene) of the present disclosure, emission of three primary colors of blue, green and red can be obtained, and a good device efficiency can be achieved.
본 발명은 인광 호스트용 화합물 및 이를 포함한 유기 발광 소자에 관한 것으로, 본 발명에 따른 인광 호스트용 화합물은 도너-어셉터-도너 (D-A-D) 구조를 채택하여 밴드갭을 크게 하도록 설계하면서 특징적으로는 어셉터 역할의 중심부로 티오잔덴(thioxanthene) 구조를 모핵으로 하고 모핵의 설폰(solfon) 구조와 대응 되는 중심원자 주변에 도너 역할로 카바졸 또는 카볼린 화합물을 결합시켜 높은 삼중항 에너지(ET)를 가지면서 높은 유리전이 온도(Tg)와 분자량이 큰 비정형의 물질로 디자인되어, 긴 수명과 전기 이동도 및 열적 안정성을 가질 수 있다.
