摘要：The present invention relates to a formulation containing at least one organicfunctional material and at least two different organic solvents, a first organic solvent Aand a second organic solvent B, wherein the first organic solvent A has a boiling point inthe range from 250 to 350°C and a viscosity of > 15 mPas, the second organic solvent Bhas a boiling point in the range from 200 to 350°C and a viscosity of ≤ 10mPas, thesolubility of the at least one organic functional material in the second organic solvent B is≥ 5 g/l, and the boiling point of the first organic solvent A is at least 10°C higher than theboiling point of the second organic solvent B; as well as to electroluminescent devicesprepared by using these formulations.
