Chiral amplification in action: Kinetic studies on the self-assembly of bis(merocyanine) dyes reveal that two phenomena that have been suggested to be of importance for natural homochirogenesis, namely, autocatalysis and the “majority-rules” effect, are both involved in the evolution of homochiral helical dye nanorods (see picture, D=supramolecular oligomer species; H1=kinetically self-assembled nanorods; H1*=H1-type aggregate precursors).
