Title:
アミノジベンゾフルオレン誘導体及びそれを用いた有機エレクトロルミネッセンス素子
Document Type and Number:
Japanese Patent JP5030534
Kind Code:
B2
Abstract:
A novel compound which is useful as a constitutional component for an organic EL device is provided by an aminodibenzofluorene derivative comprising (A) at least one dibenzofluorene structure and (B) at least one amino group in a molecule, a material for an organic electroluminescence (EL) device comprising the same, a light emitting material for an organic EL device, a light emitting organic solution, an organic EL device in which an organic compound layer comprising a single layer or plural layers including at least a light emitting layer is interposed between a pair of electrodes, wherein at leas one layer in the organic compound layer described above contains at least one kind of the aminodibenzofluorene derivative described above and an equipment comprising the same. A practical organic EL device which has a low operating voltage, a long lifetime and a high current efficiency and which provides blue light emission having an excellent color purity is materialized by using the above compound.
