“…These materials exhibit a plethora of intriguing properties, including well-defined pore structures, facile functionalization, and structural diversity, rendering them highly promising for various domains, such as adsorption , and separation, − biomedicine, − energy conversion, − sensing, − and catalysis. − Of particular interest are vinylene-linked COFs, which have garnered considerable attention due to their remarkable stability and pronounced π-electronic communication, rendering them highly prospective for photocatalysis . Nevertheless, in comparison to these COFs based on boroxine linkage, imine linkage, azine linkage or imide linkage, the construction of vinylene-linked COFs remains in an infant stage and challenging, limiting to a few kinds of monomers, including phenylacetonitrile derivatives, 2,4,6-trimethylpyridine, , tricyanomesitylene, 2,4,6-trimethyl-1,3,5-triazine, , 2,4,6-trimethylpyrylium tetrafluoroborate, 2,5-dimethylpyrazine, , benzoxazole derivatives, 2,2′,6,6′-tetramethyl-4,4′-bipyridine, phosphorus ylide derivatives, etc. However, synthesizing these monomers often involves intricate processes and even the utilization of toxic raw materials.…”
