Helicity Induction and Amplification in an Oligo(p-phenylenevinylene) Assembly through Hydrogen-Bonded Chiral Acids

Regulating the twist: Tunable supramolecular chirality is induced in an achiral helical self‐assembly (P, M; see picture) by hydrogen‐bonded chiral guest molecules (yellow and purple rods). Chiroptical probing of the π‐conjugated chromophore reveals the mechanistic pathways of chiral induction. “Maj...

Summary:Regulating the twist: Tunable supramolecular chirality is induced in an achiral helical self‐assembly (P, M; see picture) by hydrogen‐bonded chiral guest molecules (yellow and purple rods). Chiroptical probing of the π‐conjugated chromophore reveals the mechanistic pathways of chiral induction. “Majority rules” and “sergeant and soldiers” experiments give insight into the chiral amplification in the stacks.
