Abstract
The optical and chiroptical properties of an aza-HBC-oct-[5]helicene have been studied and also modulated by means of protonation or oxidation. In both cases, the generated species shows a new absorption band in the NIR region that is not present in the neutral species. This result enables this N-doped nanographene to act both as optical and, remarkably, as chiroptical switch since both the CD and CPL can be modulated by external stimuli such as redox or pH changes.
