Abstract:
A production method of an ink composition for organic EL devices comprises preparing a composition containing a polymer organic EL material and an organic solvent; and applying an electric field to the composition. Preferably, a composition containing a polymer organic EL material prepared by a coupling reaction between a halogenated aromatic compound and an aromatic boron compound in the presence of palladium catalyst or nickel catalyst, an organic solvent, and an aromatic carboxylic acid contained in an amount of 0.01-1 wt % based on the total amount of the organic solvent and aromatic carboxylic acid is prepared.
