Objects of the present invention are to provide a purification process that enables Pd and P to be removed effectively, and to provide an electroluminescent material and an electroluminescent device obtained by employing the process. The present invention relates to a process for purifying an electroluminescent material, the process involving treating, with an oxidizing agent and then with a column, an electroluminescent material that contains Pd and/or P as impurities so as to remove the Pd and/or P.

Purification process of electroluminescent material, electroluminescent material and electroluminescent device

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.
