  • Publication number: 20090226759
    Abstract: The present invention relates to partly conjugated spirobifluorene polymers which are linked in the polymer via both spiro molecule halves. The materials according to the invention display a purer emission colour and a longer life than materials according to the prior art and are therefore better suited for use in polymeric organic light-emitting diodes.

  • Publication number: 20080113468
    Abstract: The present invention relates to electronic devices comprising organic semiconductors whose content of halogens is less than 20 ppm. This increases the lifetime and the efficiency of the corresponding electronic devices, and these materials are thus better suited to use in organic electronic devices than materials with a higher halogen content. The present invention further relates to corresponding organic semiconductors and to a process for their production.

  • Publication number: 20080103279
    Abstract: The present invention relates to systems for photoenergy up-conversion comprising polymers and sensitisers, where the triplet level of the polymer is lower than the triplet level of the sensitiser. These systems exhibit higher efficiency in up-conversion and are therefore more suitable for use in devices for up-conversion than polymers as used in accordance with the prior art.

  • Publication number: 20070080343
    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 synthesise and are therefore more suitable for use in organic light-emitting diodes than comparative materials in accordance with the prior art.
