Polymer for organic electroluminescent elements, and organic electroluminescent element using cured product of same

摘要

Provided are a polymer for an organic electroluminescent element, which has high light emission efficiency and is applicable to a wet process, a cured product thereof, and an organic electroluminescent element using the cured product. The polymer for an organic electroluminescent element is represented by the following general formula (1) and includes an indolocarbazole skeleton and a polymerizable group as pendants in a repeating unit constituting a main chain, in which the polymer has a weight-average molecular weight of 1,000 to 1,000,000. An organic electroluminescent element that uses the cured product of the polymer for an organic electroluminescent element in an organic layer is also disclosed.;;R's each represent a hydrogen atom or a monovalent organic group, Y represents a divalent linking group, Z represents a substituted or unsubstituted indolocarbazolyl group having a bonding hand at an N-position, W represents a polymerizable group, m and n represent abundance molar ratios, and m represents 1 to 95 mol % and n represents 5 to 99 mol %, and 1 represents an average number of repetitions and represents 2 to 10,000.
