Abstract

The invention relates to a process for preparing a formulation comprising an organic semiconductor (OSC) and one or more organic solvents, to novel formulations obtained by this process, to their use as coating or printing inks for the preparation of organic electronic (OE) devices, especially organic field effect transistors (OFET) and organic photovoltaic (OPV) cells, to a process for preparing OE devices using the novel formulations, and to OE devices prepared from such a process or from the novel formulations.
