Chiral molecules emitting circularly polarized luminescence (CPL) have been widely investigated for their promising applications in three-dimensional (3D) displays, optical data storage and optical spintronics applications. In addition, this class of emitters has garnered significant interest as CPL offers a tantalizing solution to increasing the effective efficiency of organic light-emitting diodes (OLEDs) that contain anti-glare filters, which are required to improve the viewing contrast by limiting the reflection of external light. This requires materials to emit CPL selectively of one handedness.
