Fluorinated Copper(I) Carboxylates as Advanced Tunable p‐Dopants for Organic Light‐Emitting Diodes

Abstract

Volatile copper(I) benzoates with variable degrees of fluorination are used for p-doping of organic hole-transport layers in single-carrier devices, charge-generation layers, and in organic light-emitting diodes. The charge-transport abilities of the doped materials correlate with the degree and position of the fluorination on the aromatic ring of the carboxylate groups.
