Abstract
The present invention relates to silyl- and heteroatom-substituted compounds selected from carbazoles, dibenzofurans, dibenzothiophenes and disilylbenzophospholes of the formula (I) or (I*), to the use of the compounds of the formula (I) or (I*) in organic electronics applications, preferably in organic light-emitting diodes, to an organic light-emitting diode comprising at least one compound of the formula (I) or (I*), to a light-emitting layer comprising at least one compound of the formula (I) or (I*), to a blocking layer for holes/excitons comprising at least one compound of the formula (I) or (I*), and to an apparatus selected from the group consisting of stationary visual display units, mobile visual display units, illumination units, keyboards, items of clothing, furniture and wallpaper, comprising at least one inventive organic light-emitting diode.
