Abstract:
The present invention relates to an organic light-emitting diode which has a light-emitting layer C which contains at least one hole-conducting material CA and at least one phosphorescence emitter CB, mixtures containing at least one carbene complex in combination with at least one hole-conducting material or in combination with at least one phosphorescence emitter, and the use of mixtures containing at least one hole-conducting material and at least one phosphorescence emitter as a light-emitting layer in OLEDs for extending the lifetime of the light-emitting layer. The organic light-emitting diode according to the invention can have in at least one of the layers of the organic light-emitting diode, preferably in the hole-blocking layer and/or the electron-blocking layer and/or the light-emitting layer C, in addition to the hole-conducting material CA and the emitter CB, at least one compound selected from disilylcarbazoles, disilyldibenzofurans, disilyldibenzothiophenes, disilyldibenzophospholes, disilyldibenzothiophene-S-oxides and disilyldibenzothiophene-S,S-dioxides.
Abstract:
This invention relates to process for preparing fluorinated dyes selected from the group consisting of compounds of the general formulae (I) and (III) and mixtures thereof by reacting the corresponding compounds which do not have R12 or R30 as substituents with compounds of the general formula R12A or R30A where A is selected from the group consisting of I and Br, the compounds obtained from said process and and the use of these fluorinated dyes in electrophoretic displays.
Abstract:
Silanes comprising phenothiazine S-oxide or phenothiazine S,S-dioxide groups, organic light-emitting diodes comprising the inventive silanes, a light-emitting layer comprising at least one inventive silane and at least one triplet emitter, a process for preparing the inventive silanes and the use of the inventive silanes in organic light-emitting diodes, preferably as matrix materials and/or blocker materials for triplet emitters.
