Title:
POLYMER FOR ORGANIC ELECTROLUMINESCENT LIGHT-EMITTING ELEMENT, AND ORGANIC ELECTROLUMINESCENT ELEMENT
Document Type and Number:
Japanese Patent JP2015115405
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a polymer for organic electroluminescent light-emitting element which allows for coating without melting an underlayer when forming an organic compound layer, while suppressing increase in the drive voltage of the organic electroluminescent light-emitting element, and to provide an organic electroluminescent light-emitting element having a long term stable element performance formed by using the polymer for organic electroluminescent light-emitting element.SOLUTION: In a polymer for organic electroluminescent light-emitting element that is a solid at 25°C and used for formation of an organic electroluminescent light-emitting element having a structure where a plurality of layers are laminated between a negative electrode and a positive electrode formed on a substrate, the polymer has a polyalkyleneimine structure in the main chain skeleton, and some or all of hydrogen atoms bonded to nitrogen atoms in the polyalkyleneimine structure have a structure replaced by a π-conjugated substituent group. An organic electroluminescent light-emitting element is formed using the polymer for organic electroluminescent light-emitting element.
