摘要

A novel thia[8]helicene (BN[8]H) with B,N heteroatoms incorporated in the molecular skeleton was synthesized via Suzuki coupling reaction and intramolecular direct electrophilic C-H borylation. Its helical structure was confirmed by X-ray crystal analysis. Enantiomers BN[8]H showed the interesting responses to fluoride ion stimulation with novel sign inversion of electronic circular dichroism (ECD) and circularly polarized luminescence (CPL). TD-DFT calculations revealed that the fluoride ions significant influence the transition dipole moments and θ_u,m, resulting in circularly polarized luminescence reversal.
