Towards the room-temperature synthesis of covalent organic frameworks: a mini-review

Covalent organic frameworks (COFs) are porous and crystalline materials which are formed based on the covalent interactions between the building monomers. These materials possess fascinating properties in terms of predesignable structure, controllable morphology, and manageable functionality which distinguished them from other polymers. COFs have also high chemical and physical stability, high surface area, and high adsorption capacity that these attributes make them excellent candidates for use in different fields. However, there are several approaches for the synthesis of COFs among which room-temperature synthesis approach is a green, versatile, and popular method which is due to its exceptional properties including simplicity, easy operation, and cost-effectiveness. In this regard, this review article presents a comprehensive view of the synthesis of COFs at room temperature as well as their applications, their limitations, and also their future perspectives.
