PDY-132:F8T2 Polymer Blend Ultrafast Charge Transfer for Dipping OLED Turn-on Voltage: Consequences of Low Urbach Energy and Quicker Photoluminescence Dynamics

PDY-132 and its blends with different concentrations of poly(9,9-dioctylfluorenyl- co -3 bithiophene) F8T2 were employed as an emissive matrix for organic light-emitting devices (OLEDs).
