Abstract
A method for producing a polymer organic electronic material comprising: synthesizing a polymer organic electronic material by condensing a precursor monomer for the polymer organic electronic material in the presence of a metal catalyst, preparing a polymer organic electronic material solution by dissolving the polymer organic electronic material in an organic solvent, and removing metal ions, which originate from the metal catalyst, from the polymer organic electronic material solution by using an ion exchange resin; a polymer organic electronic material which can be obtained by the method; and an organic electroluminescent device which uses the polymer organic electronic material.
