Orderly Porous Covalent Organic Frameworks-based Materials: Superior Adsorbents for Pollutants Removal from Aqueous Solutions

“… 221 The release of radionuclides into the ecosystem poses a huge threat to the environment and seriously affects the safety of humans and other organisms. 222 , 223 Thus, the effective capture of radionuclides will bring huge gains to humanity. 223 , 224 , 225 Because of the high chemical stability and postsynthesis modification with functional groups, 226 , 227 COFs exhibit promising acid stability that can easily maintain original morphology and chemical property in acid conditions of 3 M, some even in conditions of 8 M. 217 , 228 Up to now, we have simply divided COFs into three groups, namely, single COFs, organic-group-functionalized COFs, and COF-based composites.…”

By introducing functional groups, metal ions, or other materials into COFs, the adsorption performance toward radionuclides will be significantly improved.…”

An Olefin‐based, Fluorescent Covalent Organic Framework for Selective Sensing of Aromatic Amines

“…[21][22][23][24] Owing to multiple identical binding site, porous structure guaranteed for the real-time response, sensing signals transmitted and amplified through the extended π-conjugation framework, [25,26] COFs has recently become a promising fluorescence sensing material. [27,28] However, the application of COF materials in fluorescence sensors mostly focused on detecting environmental samples such as nitro-explosives, [29][30][31] heavy metal ions, [32][33][34] pH, [35] humidity [36] etc. There is rarely report regarding the fluorescent COFs towards detect organic amines.…”

A facile imine-linked covalent organic framework doped with a carbon dot composite for the detection and removal of Hg2+ in surface water

“…In addition, an amine and sulfonyl group-based uorescent covalent organic framework was synthesized by a bottom-up hydrothermal procedure and had an effective removal capacity of Hg 2+ (99.8%). 19 Although these successful applications have been developed, the strong p-p interactions, the complicated functional monomers, the tedious preparation process or the uneconomical raw material resulted in the practical preparation and application of the photoluminescent COFs being challenging. 20,21 Therefore, it is worth designing COFs combined with quantum dots, which not only compensate for these defects but also maintain the superior adsorption ability.…”
