π-Extended D–A Type [5]Helicenes: Cyano-Based Construction and Enhanced CPL Performance

Abstract Two cyano-based D–A type [5]helicenes, N[5]Hs and P[5]Hs, were synthesized through key steps, including the Rosenmund–von Braun reaction, the Horner–Wadsworth–Emmons reaction, and elimination. Enhanced fluorescence emission is achieved with ΦFL reaching 39%; this enhance...
