<p>Provided is an organic electroluminescent element in which durability of the element during the driving at a high temperature is improved, the unevenness in in-plane luminance is reduced and the reduction in initial luminance is prevented. A material for an organic electroluminescent element, which is produced by introducing a thermally reactive group into a precursor that has been purified by sublimation. In the material for an organic electroluminescent element, the precursor is a compound having a hydrogen-binding moiety and the introduction of the thermally reactive group is the introduction of a polymerizable group into the hydrogen-binding moiety in the compound having the hydrogen-binding moiety. In the material for an organic electroluminescent element, the hydrogen-binding moiety in the precursor is located in a primary or secondary aryl amine. The material for an organic electroluminescent element is represented by general formula (1). (In general formula (1), R1's independently represent a substituent; P1 represents a vinyl group, an acryl group, a methacryl group, an epoxy group or an oxetane group; l's independently represent an integer of 0-5; l' represents an integer of 0-4; and m3 represents an integer of 0 or more; wherein R1's may together form a bond to thereby form a condensed ring which may have a substituent.)</p> |
