Synthesis and characterization of 1,8-naphthalimide with [6]helicene skeleton

A 1,8-naphthalimide with [6]helicene derivative scaffold has been designed and synthesized. The ( P)- and ( M)-enantiomers of the [6]helicene derivative were resolved by HPLC on a chiral column. The single crystal of the [6]helicene derivative exhibits an intermolecular interactions of the 1,8-naphthalimide units.
