Abstract

In the present invention, provided is an organic electroluminescent element material having a high externally taking-out quantum efficiency, which is suitable for manufacturing an element exhibiting long light emission lifetime, and also provided is an organic electroluminescent element possessing the material, a method of manufacturing the organic electroluminescent element, and a display as well as an illuminating device fitted with the organic electroluminescent element.

1 . A method of manufacturing a polymer contained in an organic electroluminescent element material, comprising the steps of:
 synthesizing the polymer from at least one monomer having an impurity content of 1000 ppm or less; and   recovering the polymer.   
     
     
         2 . The method of  claim 1 ,
 wherein the at least one monomer comprises a reactive substituent.   
     
     
         3 . The method of  claim 2 ,
 wherein the reactive substituent comprises any of the following partial structures:   
       
         
           
           
               
               
           
         
       
     
     
         4 . The method of  claim 1 ,
 wherein the polymer comprises a partial structure represented by the following Formula (1):
   —Ar1-N(Ar3)-Ar2-  Formula (1)
 
   
       wherein each of Ar1 and Ar2 independently represents an arylene group or a heteroarylene group, and Ar3 represents an aromatic hydrocarbon group or an aromatic heterocyclic group.
