Electroluminescent Polymer and Organic Electroluminescent Device

摘要

The present invention relates to an electric transfer light emitting polymer that emits light by applying an electric field thereto. Chlorine (Cl) and the sum total (SigmaM) of metal elements included in the polymer satisfies a relation of a below-described formula 1. <?in-line-formulae description="In-line Formulae" end="lead"?>SigmaM<Cl (1) <?in-line-formulae description="In-line Formulae" end="tail"?> (In this case, SigmaM designates the sum total of metal elements composed of one kind or a plurality of kinds between alkali metal elements, alkali earth metal elements, elements in the third period showing no anionic characteristics, elements in the fourth period showing no anionic characteristics and elements in the fifth period showing no anionic characteristics.)
