Room-Temperature Synthesis of Anionic Covalent Organic Framework Monolithic Materials for Efficient Capturing of Berberine Hydrochloride.
An anionic covalent organic framework (COF) was constructed using 2,5-diaminobenzenesulfonic acid as an ionic building unit. The incorporation of sulfonate functionalities endows the framework with permanent anionic sites, thereby enabling selective ion-exchange interactions with cationic species. The adsorption perfor...
