Abstract
Compositions for use in hole transporting layers (HTLs) or hole injection layers (HILs) are provided, as well as methods of making the compositions and devices fabricated from the compositions. OLED devices can be made. The compositions comprise at least one conductive conjugated polymer, at least one semiconducting matrix component that is different from the conductive conjugated polymer, and an optional dopant, and are substantially free of an insulating matrix component.
