Abstract
Polymers comprising a backbone comprising at least one arylamine repeat moiety and at least one linking moiety, wherein the linking moiety does not comprise an aryl moiety. Ink formulations and organic electronic devices such as OLEDs or OPVs can be formed from the polymers and doped polymers. The polymers can be used in a hole injection layer, hole transport layer, a hole extraction layer, or as a host material in an emissive layer. Improved stability can be achieved in organic electronic devices such as OLEDs and OPVs.
