Abstract Four novel triple thia/sulfone[6]helicenes with C 3 symmetry were obtained via Scholl reaction and sulfonation. Their helical structures were confirmed by X‐ray crystal analysis. These helicenes show dual emission of fluorescence and phosphorescence and enantiomers BTT[6]H exhibit novel dual emission of circularly polarized luminescence (CPL) or circularly polarized phosphorescence (CPP) at 77 K.
