  • Patent number: 9150687
    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.

  • Patent number: 8945420
    Abstract: The invention relates to an electro-optical liquid-crystal display which contains, as dielectric, a liquid-crystalline medium having negative dielectric anisotropy and includes a backlight which essentially only emits light having a wavelength of 400 nm or more or has, between the liquid-crystal layer and the backlight, a cut-off filter which essentially only allows light having a wavelength of 420 nm or more to pass through. In particular, the liquid-crystalline medium comprises a) a (first) dielectrically negative component (component A) which consists of one or more dielectrically negative compounds of the formula I in which the parameters have the meanings indicated in claim 2, and a further (second) dielectrically negative component (component B).
