发明名称 POLYMER FOR USE IN ORGANIC ELECTROLUMINESCENT ELEMENT AND ORGANIC ELECTROLUMINESCENT ELEMENT EMPLOYING SAME
摘要 <p>Provided are a polymer for an organic electroluminescent element, which has improved luminous efficiency and is applicable to a wet process, and an organic electroluminescent element obtained therefrom. The polymer for an organic electroluminescent element has a repeating unit represented by [-(Z) 1 - -(A) m -] n in repeating units constituting a main chain. In addition, the organic electroluminescent element includes, between an anode and a cathode laminated on a substrate, organic layers including a hole-transporting layer and a light-emitting layer, in which at least one of the organic layers contains the polymer for an organic electroluminescent element. In the repeating unit, Z represents an N-indolocarbazolyl group, A represents a repeating unit different from Z, 1 and m each represent an abundance molar ratio, and 1 is 5 to 100 mol% and m is 0 to 95 mol%, and n is 2 to 10,000.</p>
