Disclosed herein is a light emitting polymer composition which permits providing an organic electroluminescence device high in luminous efficiency and excellent in durability and forming a functional organic material layer with ease by the wet process. The light emitting polymer composition comprising a polymer component and a phosphorescent agent contained in the polymer component, wherein the polymer component is composed of a hole transporting component formed from 50 to 99 mol % of a hole transporting monomer and an electron transporting component formed from 50 to 1 mol % of an electron transporting monomer. The polymer component is a copolymer composed of 50 to 99 mol % of structural units derived from the hole transporting monomer and 50 to 1 mol % of structural units derived from the electron transporting monomer, or is composed of a hole transporting polymer obtained from the hole transporting monomer and an electron transporting polymer obtained from the electron transporting monomer, and a proportion of the hole transporting polymer to the electron transporting polymer is 50:50 to 99:1 in terms of a molar ratio reduced to the monomers. The light emitting polymer composition is used in an organic electroluminescence device and a production process thereof.
A light emitting polymer composition comprising a polymer component and a phosphorescent agent contained in the polymer component, wherein the polymer component is composed of a hole transporting component formed from 50 to 99 mol % of a hole transporting monomer and an electron transporting component formed from 50 to 1 mol % of an electron transporting monomer.
An organic electroluminescence device comprising a functional organic material layer which functions as a light emitting layer or hole transport layer and is formed by a light emitting polymer composition comprising a polymer component and a phosphorescent agent contained in the polymer component, wherein the polymer component is composed of a hole transporting component formed from 50 to 99 mol % of a hole transporting monomer and an electron transporting component formed from 50 to 1 mol % of an electron transporting monomer.
A process for producing an organic electroluminescence device, which comprises the step of forming a functional organic material layer by applying a solution of a light emitting polymer composition comprising a polymer component and a phosphorescent agent contained in the polymer component, wherein the polymer component is composed of a hole transporting component formed from 50 to 99 mol % of a hole transporting monomer and an electron transporting component formed from 50 to 1 mol % of an electron transporting monomer dissolved in an organic solvent, to the surface of a substrate and subjecting the resultant coating to a treatment for removing the organic solvent.
