Document Type and Number:
WIPO Patent Application WO/2020/071017
Kind Code:
A1
Abstract:
A mixed composition for an organic electroluminescent element according to the present invention contains an active hydrogen compound, a nitrogen-containing aromatic heterocyclic compound, and an organic solvent Y. At least one of each signal of the active hydrogen compound, said signal being assigned by using proton NMR, is shifted further towards the low magnetic-field side in the presence of a nitrogen-containing aromatic heterocyclic compound than in a system in which no nitrogen-containing aromatic heterocyclic compounds are present, and furthermore, the organic solvent Y is liquid at room temperature.
