Polythiophene compositions for improving organic light-emitting diodes

摘要

Disclosed are compositions/formulations that include: polythiophenes (A) containing recurring units represented by the following general formula (I), in which is, for example, -CH₂-CH₂-; and two additional polymers (B) and (C), each having SO₃^-M⁺ or COO^-M⁺ functional groups. Also disclosed are electroluminescent arrangements having hole-injecting layers containing the disclosed compositions.
