Abstract
Use of certain materials in hole injection or hole transport layers can improve the operational lifetimes in organic electronic devices. Compositions comprising a doped conjugated polymer, doped with a redox dopant, including iodonium salt, can increase lifetimes. Inks can be formulated and cast as films in organic electronic devices including OLEDs, PHOLEDs, and OPVs. One embodiment provides a composition with a conjugated polymer doped with a redox dopant. Non-aqueous based inks can be formulated. Iodonium salts can be used.

-72. (canceled)
A composition comprising (i) poly(3,4-di-polyether)-thiophene doped with at least one redox dopant, wherein the two polyether moieties are each an independent substitution and do not form a ring together, and each polyether moiety includes three, four, five, or six oxygen atoms in the moiety, and wherein the polyether moieties are branched moieties, and (ii) a non-aqueous solvent.
