    Abstract: Provided is an organic light-emitting diode comprising a substrate, an anode layer, optionally one or more hole injection layers, one or more hole transport layers, optionally one or more electron blocking layers, an emitting layer, optionally one or more hole blocking layers, optionally one or more electron transport layers, an electron injection layer, and a cathode, wherein either the hole injection layer, or the hole transport layer, or both of the hole injection layer and the hole transport layer, or a layer that functions as both a hole injection layer and a hole transport layer, comprises a polymer that comprises one or more triaryl aminium radical cations having the structure (S1) wherein each of R11, R12, R13, R14, R15, R21, R22, R23, R24, R25, R31, R32, R33, R34, and R35 is independently selected from the group consisting of hydrogen, deuterium halogens, amine groups, hydroxyl groups, sulfonate groups, nitro groups, and organic groups, wherein two or more of R11, R12, R13, R14, R15, R21, R22, R23, R24, R25, R31; R32; R33 R34 and R35 are optionally connected to each other to form a ring structure; wherein one or more of R11, R12, R13, R14, R15, R21, R22, R23, R24, R25, R31, R32, R33, R34, and R35 is covalently bound to the polymer, and wherein A″ is an anion.
