From: Electrical control of photon spin angular momentum in organic electroluminescent materials
a, Structure and energy levels of polymer system (F8BT) and chiral additives (aza[6]H or monoF[6]H). b, Dissymmetry factor of F8BT:(P)-aza[6]H and F8BT:(P)-monoF[6]H thin films (160 nm), annealed at 140 °C. c, J–V–L characteristics of conventional CP-OLEDs based on F8BT:(P)-aza[6]H/(P)-monoF[6]H, with or without TFB as the HTL. d, J–V–L characteristics of inverted CP-OLEDs based on F8BT:(P)-aza[6]H/(P)-monoF[6]H, with or without TCTA as the HTL. Voltage–current density curves are shown as solid lines, and voltage–luminance curves are shown as dashed lines.
