| 摘要 |
<p>The present invention includes color-variable light emitting devices which are capable of generating two independent colors, even at room temperature. The devices comprise a layer of at least one active electroluminescent polymer. This electroluminescent polymer may be accompanied by one or two redox-mediating polymer layers. The devices comprise emissive polymer layers (5), redox polymer layer, partially transparent or protective substrate (2), and electrodes (1, 3).</p> |
