Title (EN) FORMULATION OF AN ORGANIC FUNCTIONAL MATERIAL
(FR) FORMULATION D'UNE MATIÈRE ORGANIQUE FONCTIONNELLE
Abstract:
(EN) The present invention relates to a formulation containing at least one organic functional material and at least two different organic solvents, a first organic solvent A and a second organic solvent B, wherein the first organic solvent A has a boiling point in the range from 250 to 350°C and a viscosity of > 15 mPas, the second organic solvent B has a boiling point in the range from 200 to 350°C and a viscosity of ≤ 10mPas, the solubility 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 the boiling point of the second organic solvent B; as well as to electroluminescent devices prepared by using these formulations.
(FR) La présente invention concerne une formulation contenant au moins un matériau fonctionnel organique et au moins deux solvants organiques différents, un premier solvant organique A et un second solvant organique B, le premier solvant organique A ayant un point d'ébullition dans la plage de 250 à 350 °C et une viscosité > 15 mPas, le second solvant organique B ayant un point d'ébullition dans la plage de 200 à 350 °C et une viscosité ≤ 10 mPas, la solubilité du ou des matériaux fonctionnels organiques dans le second solvant organique B étant ≥ 5 g/l, et le point d'ébullition du premier solvant organique A étant d'au moins 10 °C supérieur au point d'ébullition du second solvant organique B ; ainsi que des dispositifs électroluminescents préparés à l'aide de ces formulations.
