Objects of the present invention are to provide a purification process
that enables Pd 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 a phosphorus-containing material, an electroluminescent material
that contains Pd as an impurity so as to remove the Pd.
