ABSTRACT:
Objects of the present invention are to provide a purification process that enables Pd contained in an organic electronics material to be removed effectively, to provide an electroluminescent device middle layer material purified by the process, and to provide an electroluminescent device employing the middle layer material. The present invention relates to a process for purifying an organic electronics material, the process involving treating, with a phosphorus-containing material, an organic electronics material that contains Pd as an impurity so as to remove the Pd.
