“…[109] As a result, the fundamental challenge in developing a membrane based on COFs is optimising and fully utilising the potential of their organised pore architectures. [110] COFs were initially used as porous fillers within polymeric matrix membranes to increase the availability of channels for the flow of gases, solvents, and water. [50a] Despite this, the major transport channels were still determined by the pore architectures created by polymer solution phase inversion.…”

Covalent organic frameworks (COFs) distinguish themselves from conventional materials by their exceptional combination of characteristics, including a well‐defined crystalline structure, inherent porosity, substantial surface area, remarkable design flexibility, capacity for functionalization, and chemical tunability. These attributes collectively contribute to the distinctiveness and versatility of COFs compared to traditional materials. This opens up exciting possibilities for multiple applications including energy storage, sensing, gas extraction and catalysis. The extraordinary stability of COFs in aqueous solutions and under harsh climatic conditions opens up new applications for them, including water treatment. COFs are attractive materials for tackling water pollution concerns and expanding their applications in related fields as a result of their distinctive attributes, like remarkable adsorption ability and adjustable architectures. The use of COF membranes in effluent management can improve the elimination of harmful dyes, resulting in better water quality and environmental protection. The creation of COF‐based membranes is a significant step forward in the field of water filtration and shows great potential for solving the issues faced by industrial wastewater contamination. Many published techniques provide continuous COF‐based membranes that fully utilize COFs for separations. Performance and characterization of COF‐membranes can be arbitrated with the help of various analytical and spectroscopic methods. The present study marks the most important structural characteristics and functional design methodologies of COFs in the form of thin membranes for dye separation. A discussion on the characteristics of COFs responsible for membrane separation with their synthesis and characterizations has also been done. Various reported fabrication methods of COF based membranes for dye removal are discussed concisely.
