Abstract
The invention relates to formulations comprising one or more polymers with semiconducting, charge transport, photoconducting and/or photo- or electroluminescent properties and one or more organic solvents, to their use for the preparation of electrooptical or electronic devices, including field effect transistors (FETs), electroluminescent, photovoltaic and sensor devices, in particular by ink-jet printing, and to FETs and other semiconducting or light emitting components or devices comprising the formulations.
Claims19
A formulation comprising one or more polymers wit semiconducting, charge-transport, photoconducting and/or photo- or electroluminescent properties and a solvent, which is indane or a mixture of indane and tetralin, wherein, the polymer concentration is ≦10% by weight and the solvents have a surface tension of from 32 to 40 dynes/cm and a boiling temperature of 160° C. or higher.
