Asymmetric ionic covalent organic framework membranes with tunable Turing patterns prepared via ion regulated strategy.

ABSTRACT: Advanced self-standing ionic covalent organic framework membranes (ICOFM) with strong mechanical property and high crystallinity are crucial for expanding the applications of COF membrane, yet it remains a significant challenge. Furthermore, ICOFM, which are often fragile and brittle, typically suffer from trade-off limitation between mechanical strength and high crystallinity, limiting their potential in realms such as separation processes, flexible electronics, and optoelectronics. In this work, a synthetic methodology based on an inorganic ion strategy, a previously underexplored approach, is conceived to prepare hypercrystalline and highly durable ICOFM through electrostatic-assisted interfacial monomers aggregation with enhanced diffusion, reactivity and competitive coordination regul
