INDENOFLUORENEDIONE DERIVATIVE, MATERIAL FOR ORGANIC ELECTROLUMINESCENT ELEMENT, AND ORGANIC ELECTROLUMINESCENT ELEMENT |
摘要 |
<p>An indenofluorenedione derivative having a specific structure, which is useful as a material for organic electroluminescence devices because the derivative is excellent in heat resistance and can be vapor-deposited on a substrate at moderate temperature. An organic electroluminescence device including an anode, a cathode, and an organic thin layer between the anode and the cathode, which contains the material for organic electroluminescence devices in the organic thin layer, is driven at a low driving voltage and has a long lifetime.</p> |
