Title:
The polymer for organic electroluminescence elements, and the organic electroluminescence element using it
Document Type and Number:
Japanese Patent JP5976532
Kind Code:
B2
Abstract:
Provided are a polymer for an organic electroluminescent element, which improves light emission efficiency of the element and is applicable to a wet process, and an organic electroluminescent element, which is obtained using the polymer. The polymer for an organic electroluminescent element includes a repeating unit represented by the following general formula (1) in a repeating unit constituting a main chain. Further, the organic electroluminescent element includes organic layers between an anode and a cathode laminated on a substrate, in which at least one of the organic layers includes the polymer for an organic electroluminescent element, including an indolocarbazole skeleton in the repeating unit constituting a main chain. In the general formula (1), Z represents anN-indolocarbazolyl group, W represents a charge transporting group, m and n represent molar ratios, m represents 0 to 95 mol%, and n represents 5 to 100 mol%.
