Abstract:
A pair of circularly polarized thermally activated delayed fluorescence (CP-TADF) materials (R)-ad-PXZ/(S)-ad-PXZ were obtained, which show orange-red emission at 602 nm and clear chiroptical properties both in solution and the solid state. The solution processable circularly polarized device exhibits the maximum external quantum efficiency of 9.0% and gEL value of 10-3.
