Title:
THIN FILM FOR ORGANIC ELECTROLUMINESCENCE (EL) DEVICE AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2015/034041
Kind Code:
A1
Abstract:
The present invention relates to a novel method for manufacturing a thin film of a rare-earth complex polymer with low solubility in an organic solvent and further relates to a novel organic EL device comprising a thin film of a rare-earth complex polymer obtained using this method, the thin film used as a light-emitting layer. Disclosed are the following: a method for manufacturing a rare-earth complex polymer thin film that comprises a step (1) in which a micelle-containing solvent (A) that comprises a rare-earth complex and a ferrocenyl surfactant and a micelle-containing solvent (B) that comprises a polydentate ligand and a ferrocenyl surfactant are mixed to form a mixed micelle-containing solvent, and a step (2) in which electrolysis is performed using the mixed micelle-containing solvent as an electrolyte, and formed on a positive electrode surface is a thin film of a rare-earth complex polymer that comprises the rare-earth complex and polydentate ligand; a light-emitting element that comprises an electrode and the rare-earth complex polymer thin film formed on the electrode surface; and an organic EL device that comprises an electron- and hole-transport layer on at least part of the surface of the light-emitting element and the rare-earth complex polymer thin film of the light-emitting element, and further comprises an electrode on the electron- and hole-transport layer.
