Synthesis and resolution of multi-chiral carbonyl-N embedded hetero[7]helicenes for efficient circularly polarized luminescence

Abstract

Novel carbonyl-N embedded hetero[7]helicene diastereomers incorporating axially chiral binaphthyl were facilely synthesized and separated. The separated homochiral hetero[7]helicenes exhibit intense green photoluminescence and circularly polarized luminescence (CPL) with luminescence dissymmetry...
