ORGANIC LUMINESCENCE DEVICE |
摘要 |
In an organic luminescence device formed of one or plural layers of organic films between an anode and a cathode, at least one layer is any one of a luminescence layer, an electron injection layer and an electron-transporting layer and is formed of at least a phenolic derivative of any one of formulas (1-a), (1-b), (2-a) and (2-b) characterized by having at least two phenoxide portions connected to each other via a specific divalent bond in its molecular structure. By the use of the phenolic derivative, the resultant organic luminescence device produces a high-luminance fluorescent luminescence at a low voltage for a long period of time. |
