Abstract
AbstractKinetic co‐assembly pathway induced chirality inversion along with morphology transition is of importance to understand biological processes, but still remains a challenge to realize in artificial systems. Herein, helical nanofibers consisting of phenylalanine‐based enantiomers (L/DPF) successfully transform into kinetically trapped architectures with opposite helicity through a kinetic co‐assembly pathway. By contrast, the co‐assemblies obtained by a thermodynamic pathway exhibit non‐helical structures. The formation sequence of non‐covalent interactions plays a crucial role in structural chirality of co‐assemblies. For the kinetic pathway, the hydrogen bonding between D/LPF and naphthylamide derivatives forms before π‐π stacking to facilitate the formation of helical structures with inverse handedness. This study may provide an approach to explore chirality inversion accompanied by morphology transition by manipulating the kinetic co‐assembly pathway.
