The present invention relates to novel compositions comprising an organic semiconductor (OSC) and one or more organic solvents. The composition is solid at a temperature of 25&#xb0; C. and fluid at a higher temperature and the boiling point of the solvent is at most 400&#xb0; C. Furthermore, the present invention describes the use of these compositions as inks for the preparation of organic electronic (OE) devices, especially organic photovoltaic (OPV) cells and OLED devices, to methods for preparing OE devices using the novel compositions, and to OE devices, OLED devices and OPV cells prepared from such methods and compositions.

Composition and method for preparation of organic electronic devices

The present invention relates to novel compositions comprising light emitting materials and/or charge transporting materials and one or more organic solvents having a viscosity at 25&#xb0; C. of at least 10 mPas and a boiling point of at most 400&#xb0; C., to their use as inks for the preparation of organic light emitting diode (OLED) devices, to methods for preparing OLED devices using the novel formulations, and to OLED devices prepared from such methods and formulations.

Composition having improved performance

The present invention relates to novel compositions comprising an organic semiconductor (OSC) and a wetting agent, to their use as inks for the preparation of organic electronic (OE) devices, especially organic photovoltaic (OPV) cells and organic light emitting diode (OLED) devices, to methods for preparing OE devices using the novel compositions, and to OE devices, especially OLED devices and OPV cells prepared from such methods and compositions. The efficiency of an OE device with the inclusion of 1% volatile surfactant was 13.5 cd/A at 100 cd/m2.

Compositions comprising organic semiconducting compounds

The present invention relates to novel compositions comprising light emitting materials and/or charge transport materials and a polymeric binder, to their use as conducting inks for the preparation of organic light emitting diode (OLED) devices, to methods for preparing OLED devices using the novel formulations, and to OLED devices prepared from such methods and formulations.
