Title:
COPOLYMER, MATERIAL FOR ELECTRONIC ELEMENT, MATERIAL FOR ORGANIC ELECTROLUMINESCENT ELEMENT, AND ORGANIC ELECTROLUMINESCENT ELEMENT
Document Type and Number:
WIPO Patent Application WO/2016/159293
Kind Code:
A1
Abstract:
Provided are: a copolymer which has positive hole transport properties and solubility and which is suitable for the formation of films by a coating method; a material for an electronic element and a material for an organic EL element which comprise the copolymer; a solution containing the copolymer; and an organic EL element. Provided are a copolymer containing a structural unit A represented by general formula (A), a structural unit B represented by general formula (B), and at least one structural unit C selected from a structural unit C1 represented by general formula (C1) and a structural unit C2 represented by general formula (C2), an organic electroluminescent element, an electronic device equipped with the organic electroluminescent element, a material for an organic electroluminescent element which comprises the copolymer, and a coating liquid.
