Abstract:
A composition comprising: at least one conjugated polymer, at least one second polymer comprising repeat units represented by: (I) optionally, —[CH2—CH(Ph-OH)]— and (II) —[CH2—CH(Ph-OR)]— wherein Ph is a phenyl ring and R comprises a fluorinated group, an alkyl group, an alkylsulfonic acid group, an alkylene oxide group, or a combination thereof is described. Other polymers can be used as second polymer including polymers comprising modified naphthol side groups. The composition can be used in hole injection and hole transport layers for organic electronic devices. Increased lifetime and better processability can be achieved. Versatility with useful OLED emitters can be achieved. Ink formulations can be adapted for ink jet printing. The conjugated polymer can be a polythiophene. Applications include OLEDs and OPVs.
