Abstract

The invention relates to a method for producing polyfluoroanthenes containing repeat units of general formula (I), said method consisting of the following steps: a) a monomer fluoroanthene derivative of formula IIa is produced; b) optionally the monomer fluoroanthene derivative of formula IIa is converted into another monomer fluoroanthene derivative of formula IIb; and c) the monomer fluoroanthene derivative of formula IIa or IIb is polymerised, optionally together with at least one other comonomer. The invention also relates to polyfluoroanthenes that can be produced according to the inventive method, films, a light-emitting layer containing or consisting of at least one inventive polyfluoroanthene, OLEDs containing at least one inventive polyfluoroanthene, OLEDs containing an inventive light-emitting layer, a device containing an inventive OLED, and the use of the inventive polyfluoroanthene emitter substances in OLEDs.
