Radial growth of twist-stacked covalent organic framework nanofibers.

ABSTRACT: Engineering symmetry breaking is a fertile ground to develop innovative materials with fascinating properties. Herein, we introduce crystallographically incompatible rotation element into two-dimensional polymers and construct twist-stacked covalent organic framework nanofibers (abbreviated as t-COFs). These t-COFs are derived from polymerization between 2,4,6-triformylphloroglucinol and diamines modulated by monodentate alkylamine. Comprehensive electron microscopy analysis reveals their well-defined fibrous morphology and twist-stacking details. The time-dependent growth process study discloses a new radial growth pattern, which enables t-COFs to inherit twist-stacking from hexagonal macrocycle nanotube intermediate. Intriguingly, the twist-stacking mode is found to be intrinsic when usi
