Converting CO2 into value‐added chemicals to solve the issues caused by carbon emission is promising but challenging. Herein, by embedding metal ions (Co2+, Ni2+, Cu2+, and Zn2+) into an imidazole‐linked robust photosensitive covalent organic framework (PyPor‐COF), effective photocatalysts for CO2 conversion are rationally designed and constructed. Characterizations display that all of the metallized...
In order to overcome the limitations of supramolecular organic cages for their incomplete accessibility of active sites in the solid state and uneasy recyclability in liquid solution, herein a nitrogen‐rich organic cage is rationally linked into framework systems and four isoreticular covalent organic frameworks (COFs), that is, Cage‐TFB‐COF, Cage‐NTBA‐COF, Cage‐TFPB‐COF, and Cage‐TFPT‐COF, are successfully...
A highly porous metal‐organic framework (MOF) incorporating two kinds of second building units (SBUs), i.e., dimeric paddlewheel (Zn2(COO)4) and tetrameric (Zn4(O)(CO2)6), is successfully assembled by the reaction of a tricarboxylate ligand with ZnII ion. Subsequently, single‐crystal‐to‐single‐crystal metal cation exchange using the constructed MOF is investigated, and the results show that CuII and...
On page 2334, R. Q. Zou, Y. L. Zhao, and co‐workers present a porous metal‐organic framework (MOF) that serves as a platform for studying the metal exchange effect on both CO2 adsorption and catalytic fixation. The effect is demonstrated by catalytic CO2 cycloaddition with propylene oxide to produce propylene carbonate. Molecular dynamic simulations are carried out to further confirm the catalytic...
