Abstract
Compositions comprising at least one hole transport material, such as a conjugated polymer, and at least one dopant, providing improved thermal stability. Compositions can be applied to substrates and used in HIL and HTL layers and organic electronic devices such as light emitting devices such as OLEDs or OPVs. The conjugated polymer can be a polythiophene, including a 3,4-substituted polythiophene or a regioregular polythiophene. The dopant can be a silver salt such as silver tetrakis(pentafluorophenyl)borate. Improved methods of making dopant are provided.
