Abstract:
The efficient synthetic route was disclosed to prepare optically active triarylborane-based [5]helicenes, 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 (glum > 5 × 10-3).

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
