A family of chiral nanographenes bearing [6]helicene units has been synthesized via the classical Scholl reaction. Inserting the [6]helicene unit into the parent nanographene skeleton can result in different structural topologies and optoelectric properties. Moreover, the isolated enantiomers exhibit attractive chiroptical properties.
