Controlling the photophysics of double helicenes is facilely achieved by variation of the terminal aromatic rings. Compared to the thiadiazole-fused and all-carbon analogs, triazole-fused double helicene shows significantly enhanced emission with near-unity quantum yield, and high circularly polarized luminescence brightness of up to 30.1 M⁻¹ cm⁻¹, as well as excellent ambipolar redox behavior.
