The efficient synthetic route was disclosed to prepare optically active triarylborane-based 5helicenes, 7B-PhHC and 7B5N-PhHC. Their emission wavelengths are tunable by both the chemical structure modification and the tuning of excited state charge transfer dynamics via selection of appropriate solvents or addition of external F–, enabling the full-color circularly polarized luminescence with moderate to good quantum yields (0.07–0.51) and high luminescence dissymmetry factors (g lum > 5 × 10–3).
