COMPOSITION FOR ORGANIC ELECTROLUMINESCENT ELEMENT AND ORGANIC ELECTROLUMINESCENT ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a composition for organic electroluminescent element which is used suitably for forming a hole-injecting/transporting layer of an organic electroluminescent element by a wet film-forming method. SOLUTION: The solution composition is prepared by dissolving a hole transporting material such as an aromatic diamine compound and an electron-accepting compound such as tri(pentafluorophenyl) boron in a solvent, and the composition for organic electroluminescent element contains ether group solvent and / or ester group solvent having water solubility of≤1 wt% at 25°C by≥10 wt% as a concentration of the composition.
