摘要 |
<p>The present invention relates to electroluminescent polymers which contain at least one structural unit which includes at least one phosphorescent emitter unit, to processes for the preparation of these polymers, to mixtures (also called blends), solutions and formulations which comprise these polymers, to the use of these polymers in electronic devices, in particular in organic electro-luminescent devices, so-called OLEDs (OLED=organic light emitting diodes), and to electronic devices containing these polymers. The polymers according to the invention exhibit improved efficiency and a longer lifetime, in particular on use in OLEDs.</p> |
