Abstract
The present invention relates to organic semiconductors which contain structural units L=X and in addition structural units which emit light from the triplet state. The materials according to the invention are more soluble and easier to synthesize and are therefore more suitable for use in organic light-emitting diodes than comparative materials in accordance with the prior art.
