• Sign inversions of circularly polarized luminescence (CPL) for the hydro[5]helicene and [5]helicene derivatives were discovered and studied experimentally and theoretically. The inverted CPL signs from the hydro[5]helicene to [5]helicene derivatives were realized by one-step oxidation. The introduction of triphenylamine (TPA) subunits into the helical skeletons also led to the sign inversion of CPL only when there existed an enhanced intramolecular charge-transfer state with a small enough E gap . Sign inversions of CPL by fine-tuning operations on structures of helical compounds were realized by one step-oxidation or TPA-modification.
