摘要:
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.
摘要:
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.

摘要:
The present invention relates to novel polymers which comprise spirobifluorene and fluorine units of the formulae (I) and (II) and may further comprise additional structural elements which may have charge transport properties, hole transport properties and/or electron transport properties.Such materials display a significantly improved property profile in electronic components, particularly when used in a PLED, in particular as electroluminescence material, in organic integrated circuits (O-ICs), organic field effect transistors (OFETs), organic thin film transistors (OTFTs), organic solar cells (O-SCs) or organic laser diodes (O lasers).
摘要:
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.
