NOVEL MATERIALS FOR ELECTROLUMINESCENCE |
摘要 |
<p>The present invention relates to mixtures and to conjugated polymers which contain bridged carbazole structural units and structural units which emit light from the triplet state. The inventive mixtures exhibit improved efficiencies and reduced operating voltages and are therefore better suited to use in organic light-emitting diodes than comparative materials which do not comprise these units.</p> |
