“…This method has excellent properties like simplicity and ease of process which does not need high temperature. [25,34,35] The room-temperature production approach has many other benefits, some of which are mentioned in the following. For the preparation of COFs, many building monomers are unstable at high temperatures, so, the ambienttemperature technique has importance in this regard.…”

Covalent organic frameworks (COFs), as a new class of crystalline, well‐ordered, and porous materials with intermittent constructions, are formed via organic structural parts connected through covalent bonds. These materials have been employed in several fields comprising pollutant adsorption and separation, catalysis, electrical conductivity, gas storage, etc. The preparation of COFs is mainly applied in tubes with high temperatures and degassing treatment. Furthermore, the reaction medium is involved in toxic organic solvents like toluene, dioxane, mesitylene, acetonitrile, and so on. Hence, discovering clean medium and green approaches has attracted wide attention. Recently, facile, less dangerous, and greener methods have been developed for COFs synthesis in diverse applications like performing the reaction at ambient temperature or employing aqueous solvents, ionic liquids, and a mixture of organic solvents/water. This review article summarizes the eco‐friendly production approaches of COFs for diverse applications.
