Patent number: 9150687Abstract: 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.Type: GrantFiled: September 20, 2005Date of Patent: October 6, 2015Assignee: Merck Patent GmbHInventors: Hubert Spreitzer, Aurélie Ludemann, René Scheurich, Niels Schulte, Arne Büsing, Philipp Stössel

Patent number: 8173276Abstract: 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.Type: GrantFiled: December 16, 2009Date of Patent: May 8, 2012Assignee: Merck Patent GmbHInventors: Susanne Heun, René Scheurich, Arne Büsing, Aurelie Falcou, Anja Gerhard, Philipp Stössel, Horst Vestweber

Patent number: 7901766Abstract: The invention relates to electronic devices whose electronic properties can surprisingly be improved to a significant degree by inserting at least one crosslinkable polymeric buffer layer, preferably a cationically crosslinkable polymeric buffer layer, between the conductive doped polymer and the organic semiconductor layer. Particularly good properties are obtained with a buffer layer in which crosslinking is thermally induced, i.e. by raising the temperature to 50 to 250° C. Alternatively, crosslinking can be radiation-induced by adding a photoacid. Moreover, such a buffer layer can be advantageously applied by means of printing techniques, especially inkjet printing, as the ideal temperature for the thermal treatment is independent of the glass transition temperature of the material. This avoids having to rely on material that has a low molecular weight, making it possible to apply the layer by means of printing techniques.Type: GrantFiled: September 4, 2004Date of Patent: March 8, 2011Assignee: Merck Patent GmbHInventors: David Christoph Müller, Nina Riegel, Frank Meyer, René Scheurich, Aurélie Falcou, Klaus Meerholz
