Iridium-based luminescent compounds having phenylpyridine moieties with organosilicon group, and organic electroluminescence devices using the compounds as color-producing materials

摘要

Disclosed are iridium-based luminescent compounds having phenylpyridine moieties with an organosilicon group, and organic electroluminescence devices using the compounds as color-producing materials. The luminescent compounds have the structure of Formula 1 below:; wherein L₁, L₂, L₃, R₁, R₂ and R₃, which may be identical to or different from each other, are each independently selected from the group consisting of aryl, alkoxy, alkyl, and groups of Formula 3 below: ;
