LAMINATE STRUCTURE, POLYMER, ELECTROLUMINESCENT ELEMENT, AND PHOTOELECTRIC CONVERSION ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a laminate structure for achieving an electroluminescent element that emits light at high luminance and a photoelectric conversion element with high photoelectric conversion efficiency.

SOLUTION: A laminate structure comprises a first electrode, a second electrode, a light emission layer or a charge separation layer located between the first electrode and the second electrode, and a layer which is located between the light emission layer or the charge separation layer and the first electrode and which includes a polymer with a repeating unit including one or more ionic groups selected from particular two groups and particular one or more polar groups. A polymer comprises one or more repeating units selected from particular four repeating units including an aromatic group as a repeating unit including one or more ionic group selected from particular two groups and particular one or more polar groups. An electroluminescent element comprises the laminate structure, and a photoelectric conversion element comprises the laminate structure.
