A composition for ink jet printing an opto-electrical device, the composition comprising: an electroluminescent or charge transporting organic material; and a high boiling point solvent having a boiling point higher than water.

Solvents for PEDOT-solutions for ink-jet printing

A light-emissive device is prepared by depositing a polymer layer on a substrate. The deposition process utilizes a formulation comprising a conjugated polymer dissolved in a solvent, the solvent including a trialkyl-substituted aromatic hydrocarbon wherein at least two of the alkyl substituents are ortho to one another. The deposition of the polymer layer on the substrate may be accomplished by an ink-jet method.

Light-emissive device

Method for fabricating a polymer L.E.D.

A formulation for depositing a material on a substrate, the formulation comprising the material to be deposited on the substrate dissolved in a solvent system comprising a first solvent component having a relatively high boiling point and which exhibits a relatively low solubility with respect to the material to be deposited, and a second solvent component having a relatively low boiling point and which exhibits a relatively high solubility with respect to the material to be deposited.

Formulation and method for depositing a material on a substrate

A formulation for depositing a polymer layer in the production of a light-emissive device, the formulation including a conjugated polymer dissolved in a solvent, the solvent including a trialkyl-substituted aromatic hydrocarbon, at least two of the alkyl substituents being ortho to one another; and the use of such formulation in the deposition of a polymer layer on a substrate by an ink-jet method.
