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.
本发明涉及混合物和共轭聚合物,其中包含桥接的
咔唑结构单元和从三重态发射光的结构单元。本发明的混合物表现出更高的效率和降低的操作电压,因此比不含这些单元的比较材料更适合用于有机发光二极管。
