Abstract: Covalent organic frameworks (COFs) are two-dimensional or three-dimensional crystalline porous structures formed by the covalent bonding of organic monomers. As an emerging crystalline porous material, COFs have been widely used in various fields such as gas storage, catalysis, sensing, and drug delivery. In recent years, COFs have shown immense potential in analytical chemistry because of their low density, large surface area, and controllable structure. This paper reviews the application of porous COFs and their composites in sample pretreatment, including dispersive solid-phase extraction, solid phase micro-extraction, and magnetic solid phase extraction.

Key words: covalent organic frameworks (COFs), sample pretreatment, review
