Abstract

See full text

A method including combining at least one first compound in a neutral form with at least one ionic dopant in a first solvent system to provide a first doped reaction product, isolating the first doped reaction product in solid form, and combining the isolated first doped reaction product with at least one conjugated polymer in neutral form in a second solvent system to form a second doped reaction product including an oxidized form of the conjugated polymer a neutral form of the first compound is described. Advantages include better stability, ease of use, and lower metal content. Applications include organic electronic devices including OLEDs.
