Title (EN) DEEP-BLUE PHOSPHORESCENT IRIDIUM COMPLEX USING AN N-METHYLIMIDAZOLYL TRIAZOLE ANCILLARY LIGAND
(FR) COMPLEXE PHOSPHORESCENT BLEU FONCÉ DE L'IRIDIUM UTILISANT UN LIGAND AUXILIAIRE N-MÉTHYLIMIDAZOLYLTRIAZOLE
(KO) 엔-메틸이미다졸릴트리아졸 보조 리간드를 이용한 짙은 청색 인광 이리듐 착화합물
Abstract: front page image
(EN)The present invention relates to a blue phosphorescent iridium complex as expressed in chemical formula 1. The iridium complex of the present invention may exhibit a deeper blue color in a blue light-emitting region, and significantly improve phosphorescent quantum yield and light-emitting efficiency as compared to conventional iridium complexes. The light-emitting material comprising such an iridium complex may be used in a light-emitting layer of an organic light-emitting diode, and used in a display device.
(FR)La présente invention porte sur un complexe phosphorescent bleu de l'iridium tel que représenté par la formule chimique 1. Le complexe de l'iridium de la présente invention peut présenter une couleur bleue plus foncée dans une région d'électroluminescence bleue et améliorer considérablement le rendement quantique de phosphorescence et le rendement d'électroluminescence par comparaison avec des complexes classiques de l'iridium. Le matériau électroluminescent comprenant un tel complexe de l'iridium peut être utilisé dans une couche électroluminescente d'une diode électroluminescente organique et utilisé dans un dispositif d'affichage.
(KO)본 발명은 화학식 1로 표시되는 청색 인광 이리듐 착화합물을 개시한다. 본 발명에 따른 이리듐 착화합물을 이용하면, 종래의 이리듐 착화합물에 비하여 청색 발광 영역에서 더 진한 청색을 나타내고, 인광 양자 수율(quantum yield) 및 발광 효율이 매우 개선되고, 이러한 이리듐 착화합물을 포함한 발광 물질은 유기 발광 소자의 발광층에 이용될 수 있으며, 디스플레이 장치에 활용될 수 있다.
