Title:
POLYMER FOR ORGANIC ELECTROLUMINESCENT ELEMENTS, AND ORGANIC ELECTROLUMINESCENT ELEMENT USING CURED PRODUCT OF SAME
Document Type and Number:
WIPO Patent Application WO/2012/132556
Kind Code:
A1
Abstract:
Provided are: a polymer for organic electroluminescent elements, which has high luminous efficiency and is applicable to a wet process; a cured product of the polymer for organic electroluminescent elements; and an organic electroluminescent element which uses the cured product. This polymer for organic electroluminescent elements is represented by general formula (1) and has an indolocarbazole skeleton and a polymerizable group in the form of pendants in a repeating unit that constitutes the main chain, while having a weight average molecular weight of 1,000-1,000,000. Also disclosed is an organic electroluminescent element which uses a cured product of this polymer for organic electroluminescent elements in an organic layer. In general formula (1), R represents 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 the N-position; W represents a polymerizable group; m and n represent molar proportions, with m being 1-95% by mole and n being 5-99% by mole; and l represents an average number of repetition, that is 2-10,000.
