Abstract
The present invention relates to novel compositions comprising one or more polymeric organic semiconducting (OSC) compounds and one or more organic solvents. The composition preferably comprises 3,4-dimethyl anisole as solvent. 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 organic light emitting diodes (OLED) devices, to methods for preparing OE devices using the novel formulations, and to OE devices, OLED devices and OPV cells prepared from such methods and formulations.
