ABSTRACT:
The invention relates to fluoranthene derivatives of the general formula (I)in which R1, R2, R3and a are each defined according to the description, with the proviso that at least one of the R1or R2radicals is not hydrogen, to processes for their preparation and to the use of the fluoranthene derivatives as emitter molecules in organic light-emitting diodes (OLEDs), to a light-emitting layer comprising the inventive fluoranthene derivatives as emitter molecules, to an OLED comprising the inventive light-emitting layer and to devices comprising the inventive OLED.
