- •
New polymer blend F81-xSYx used as emissive layer in PLEDs exhibit high efficiency.
- •
Difference between HOMOs of F8 and SY is exploited to reduce the hole mobility.
- •
SY molecules in F8 act as hole traps and dictate the overall transport properties.
- •
High efficiency of F81-xSYx based PLEDs is due to the balanced charge transport.
