ELECTROLUMINESCENT POLYMER AND ORGARNIC ELECTROLUMINESCENT DEVICE

摘要

Disclosed is an electroluminescent polymer which emits light when an electric field is applied thereto. Chlorine (Cl) and the total of metal elements (SigmaM) contained in the polymer satisfy the following relation (1). SigmaM < Cl (1) (In this connection, SigmaM is the total of one or more kinds of metal elements selected from alkali metal elements, alkaline earth metal elements, third row elements of the periodic table not exhibiting anionic properties, fourth row elements of the periodic table not exhibiting anionic properties, and fifth row elements of the periodic table not exhibiting anionic properties.)
