Title:
POLYMER COMPOUND AND LIGHT-EMITTING ELEMENT USING SAME
Document Type and Number:
WIPO Patent Application WO/2023/176304
Kind Code:
A1
Abstract:
Provided is a polymer compound which is useful in manufacturing light-emitting elements with outstanding luminance lifespans. The present invention is a polymer compound including two types or more of the constituent unit represented in formula (0-1). [In the formula, a represents an integer from 0 to 6; and R1 represents an alkyl group, a cycloalkyl group, an alkoxy group, a cycloalkoxy group, an aryl group, an aryloxy group, a monovalent heterocyclic group, a substituted amino group, or a halogen atom, and these groups may have substituent groups. If there are a plurality of R1, they may be the same or different. R0 represents a hydrogen atom, an alkyl group, a cycloalkyl group, an alkoxy group, a cycloalkoxy group, an aryl group, and aryloxy group, a monovalent heterocyclic group, a substituted amino group, or a halogen atom, and these groups may have substituent groups. The plurality of R0 may be the same or different. At least one of R0 represents an aryl group having a specific structure.]
