Abstract
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.
