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. 

Synthesis of phenyl-substituted polyfluoroanthenes and the use thereof

A substituted fluoranthene, a light emitting layer including the substituted fluoranthene, a diode including the substituted fluoranthene, and a visual display unit including the substituted fluoranthene.

Synthesis of phenyl-substituted fluoranthenes by a diesel-alder and the use thereof

The present invention relates to a process for preparing propylene polymer compositions in at least two-stage process wherein, in a first stage, a propylene homopolymer or a propylene copolymer comprising propylene and at least a CZ-CIO-1-alkenes other than propylene, containing at least 85% by weight of propylene, is prepared by polymerization and, in a second stage, ethylene and at least a comonomer selected from propylene and C4-C,o1alkenes are polymerized to give an ethylene polymer, comprising at least 90% by weight of ethylene, wherein the amount of the ethylene polymer in the propylene polymer composition ranges from 10 to 50% by weight and the propylene polymer composition has a melt flow rate MFR, in accordance with ISO 1133 at 230&#xb0; C. and 2.16 kg, of from 2 to 50 g/10 min.

At least two-stage process for preparing propylene polymer compositions

The invention relates to fluoranthene derivatives of the general formula (I) in which R, R, Rand a are each defined according to the description, with the proviso that at least one of the Ror Rradicals 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.
