π-Expanded 6Helicene-Containing Nanographenes: Synthesis, Structures, and Chiroptical Properties

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 exhibi...

Description
Summary: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.A family of chiral nanographenes bearing [6]helicene units has been synthesized via the classical Scholl reaction.
