A Facile Micelle-Assisted Self-Assembly Method to Covalent Organic Framework Helical Nanoarchitectures

Abstract

We present a micelle-assisted self-assembly strategy for synthesizing covalent organic framework (COF) helical hollow nanoribbons by using achiral monomers and surfactants. The process involves polymerization of nanowires within rod-like micelle cores, followed by their attachment to form helical nanoribbons and solvothermal crystallization to create hollow COF architectures. This method allows for the controllable synthesis of COF helical nanostructures with tunable pitch and morphology and can be extended to other COF helical architectures by variation of the amine monomer. This strategy provides new insights into designing COF helical nanostructures using achiral building blocks within micellar systems.
