The present invention relates to novel formulations comprising an organic semiconductor (OSC) and one or more organic solvents. The formulation comprises a viscosity at 25° C. of less than 15 mPas and the boiling point of the solvent is at most 400° C. Furthermore, the present invention describes the use of these formulations 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 formulations, and to OE devices, OLED devices and OPV cells prepared from such methods and formulations.

Formulation and method for preparation of organic electronic devices

The present invention relates to formulations for the preparation of organic electronic devices (OLEDs) which comprise (A) at least one specific ester solvent containing an aromatic group and (B) at least one organic functional material selected from organic conductors, organic semiconductors, organic fluorescent compounds, organic phosphorescent compounds, organic light-absorbent compounds, organic light-sensitive compounds, organic photosensitisation agents and other organic photoactive compounds, selected from organometallic complexes of transition metals, rare earth metals, lanthanides and actinides.

Esters containing aromatic groups as solvents for organic electronic formulations

The present invention relates to formulations containing at least one organic functional material and at least a first organic solvent, wherein said first organic solvent is an alkyl benzoate solvent, as well as to electronic devices prepared by using these formulations.

Formulation of an organic functional material

The present invention relates to a formulation comprising at least one organofunctional material which can be employed for the production of functional layers of electronic devices, and at least one aromatic compound. The present invention furthermore relates to electronic devices which are obtainable from these formulations.
