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 invention relates to copolymers that comprise the structural units according to formula (1) and iridium complexes as triplet emissives. The inventive polymers are better suited to the use in organic light-emitting diodes than comparable prior art materials.
摘要:
The invention relates to a method for the production of high-purity, heteroleptic, ortho-metallated, organometallic compounds of application as a functional material for colouring components in a wide range of applications within the widest sense of the electronics industry. A method is thus used for the cleavage of a bridged metal dimer with organometallic substances. Dihalo complexes, which may be used as monomers for polymerisations, in particular, may be produced thus.

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.
