The organic electroluminescence device utilizes a novel combination of a biscarbazole derivative compound as a phospherescent host materials and an orgaphosphorescent material as a red phosphorescent dopant material in the light emitting region of the device, where the biscarbazole derivative compound is represented by a formula (1); wherein the red phosphorescent dopant material is a phosphorescent organometallic complex having a substituted chemical structure represented by one of the partial chemical structures represented by a formulas (D1), (D2) and (D3).
ligand with a d-π-A structure and synthesized its corresponding Eu (III) and Tb (III) complexes. The structures of the complexes were analyzed by single crystal X-ray diffraction. It was surprisingly that the fluorescence emission intensity of the Eu(III) complex increases significantly once the solvent was added, indicating that the fluorescence could be activated by the solvent. However, it was confirmed
