Abstract
Official abstract text for this publication.
The present invention relates to novel formulations comprising an organic semiconductor (OSC) and one or more organic solvents. The formulation comprises a dimethyl anisole solvent. 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composition comprising one or more organic semiconducting compounds (OSC) having a molecular weight of at least 800 g/mol and of at most 5000 g/mol, and one or more organic solvents, characterized in that at least 60% by weight said organic solvent is a dimethylanisole. 2. The composition according to claim 1 , wherein said dimethyl anisole is 3,4-dimethylanisole. 3. The composition according to claim 1 , wher…
