Transcription and Amplification of Molecular Chirality to Oppositely Biased Supramolecular π Helices

Let's twist again: Transcription of molecular chirality from common stereogenic centers to amplified supramolecular chirality during the coassembly of gel‐forming π‐conjugated molecules by inverted helicity results in the formation of longitudinally fused M and P helices. This “sergeants and so...

Summary:Let's twist again: Transcription of molecular chirality from common stereogenic centers to amplified supramolecular chirality during the coassembly of gel‐forming π‐conjugated molecules by inverted helicity results in the formation of longitudinally fused M and P helices. This “sergeants and soldiers” approach to coassembly under stereomutation has been confirmed by CD and AFM techniques (see picture).
