Title:
POLYMER FOR ORGANIC ELECTROLUMINESCENT ELEMENT AND ORGANIC ELECTROLUMINESCENT ELEMENT
Document Type and Number:
WIPO Patent Application WO/2019/181564
Kind Code:
A1
Abstract:
Provided is a polymer for an organic electroluminescent element, the polymer having high light emission efficiency and high durability, and being applicable to a wet process. This organic electroluminescent element is obtained by laminating a positive electrode, an organic layer and negative electrode on a substrate, and is characterized in that a material containing a polymer for an organic electroluminescent element, the polymer having a polyphenylene main chain that has a five-ring condensed heterocyclic structure in a side chain, is used in at least one layer of the organic layer.
