POLYMER FOR ORGANIC ELECTROLUMINESCENT ELEMENT, AND ORGANIC ELECTROLUMINESCENT ELEMENT USING SAME

摘要

Disclosed is a polymer for an organic electroluminescent element, which is capable of improving the luminous efficiency of the element, while being applicable to a wet process. Also disclosed is an organic electroluminescent element which is obtained using the polymer for an organic electroluminescent element. The polymer for an organic electroluminescent element has a repeating unit represented by general formula (1) in the repeating unit that constitutes the main chain. The organic electroluminescent element comprises organic layers between a positive electrode and a negative electrode that are laminated on a substrate, and at least one of the organic layers contains the above-described polymer for an organic electroluminescent element having an indolocarbazole skeleton in the repeating unit that constitutes the main chain. In general formula (1), Z represents an N-indolocarbazolyl group; W represents a charge transporting group; and m and n represent the molar proportions, namely, m represents 0-95% by mole and n represents 5-100% by mole.
