HIGH MOLECULAR COMPOUND, ORGANIC ELECTROLUMINESCENCE ELEMENT MATERIAL, ORGANIC ELECTROLUMINESCENCE ELEMENT, AND ELECTRONIC DEVICE

摘要

Provided is a high-molecular compound having a structural unit (A) and a structural unit (B) differing from each other, wherein the structural unit (A) is represented by the following general formula (A-1) and the structural unit (B) has a structure containing an arylene group or a heteroarylene group. The high-molecular compound can produce an organic EL device having a long lifetime, and is favorable as a forming material for organic EL devices. [In the formula, Ar^A represents a linking group having a fluorene skeleton, L¹, L², Ar¹ and Ar² each are a predetermined group, at least one of Ar¹ and Ar² is a monovalent organic group represented by the following general formula (a). (In the formula, X represents a divalent group selected from —O—, —S—, —N(R^x)—, etc., R¹ and R² each represent a substituent, p is an integer of 0 to 3, q is an integer of 0 to 4, and * indicates a bonding position to L¹ or L².)]
