Title:
POLYMER, COMPOSITION FOR ORGANIC ELECTROLUMINESCENT ELEMENT, ORGANIC ELECTROLUMINESCENT ELEMENT, ORGANIC EL DISPLAY DEVICE, ORGANIC EL LIGHTING, AND MANUFACTURING METHOD FOR ORGANIC ELECTROLUMINESCENT ELEMENT
Document Type and Number:
WIPO Patent Application WO/2019/177175
Kind Code:
A1
Abstract:
Provided are: a polymer that has a high hole-injection/transport capacity and that is highly durable; and a composition for an organic electroluminescent element that contains the polymer. The polymer has a repeating unit represented by formula (1) or a repeating unit represented by formula (2). In the formulas: Ar1 and Ar2 represent optionally substituted aromatic hydrocarbon groups or optionally substituted aromatic heterocyclic groups; X represents –C(R7)(R8)-, -N(R9)-, or –C(R11)(R12)-C(R13)(R14)-; R1 and R2 as well as R3 and R6 each independently represent an optionally substituted alkyl group; R4 and R5 each independently represent an optionally substituted alkyl group, an optionally substituted alkoxy group, or an optionally substituted aralkyl group; and R7 through R9 as well as R11 through R14 each independently represents hydrogen, an optionally substituted alkyl group, an optionally substituted aralkyl group, or an optionally substituted aromatic hydrocarbon group.
