ORGANIC LIGHT-EMITTING DEVICES WITH MULTIPLE HOLE INJECTION LAYERS CONTAINING FULLERENE |
摘要 |
The present invention provides layered hole injection structures including one or more layers of fullerenes for application in an organic electroluminescent device. The layered structures include a bi-layered structure including an electrically conductive layer serving as electrical contact to external circuit and a fullerene layer sandwiched between the conductive layer and a hole transport layer. The layered structure may also includes a tri-layered structure stacked sequentially including a first electrically conductive layer, a fullerene layer and a hole injection layer material selected from thermally stable molecules such as CuPc. The layered structure may also include a four-layered structure stacked sequentially including a first electrically conductive layer, a fullerene layer on the conductive layer, a noble metal layer on the fullerene layer and another fullerene layer on the noble metal layer.
