Summary: In this study, three new zinc(II) complexes were synthesized to further investigate their molecular structures and crystal packing. X-ray structural analysis revealed that the intramolecular resonance-assisted hydrogen bond ring remained intact in the zinc(II) complexes, and the presence of halogen bonds resulted in one-dimensional supramolecular polymers in the crystal packing. In the catalytic experiments, it was found that the zinc(II) complex Zn4 exhibited high catalytic activity and could efficiently catalyze the cycloaddition reaction to produce cyclic carbonates under solvent-free conditions.

Summary: An unprecedented correlation between the catalytic activity of a Zr-based UiO-type MOF and its degree of interpenetration is reported. Partially interpenetrated MOFs exhibit higher catalytic activity, possibly due to higher substrate concentration and close arrangement of catalytically active sites in the interpenetrated structure.

Summary: Metal-organic frameworks (MOFs) membranes have great potential in ion separation, with UiO-67 membranes synthesized using a washing-assisted secondary growing method showing high Li+ permeance and excellent Li+/Mg2+ selectivity. The high selectivity is associated with the difference in ion dehydration between Li+ and Mg2+ in the membrane channels.

Summary: A post-synthetic modification of Zr-MOF using ionic nitrogen-based functional groups allows for the catalytic cycloaddition reaction of CO2 with epoxides. The functionalized MOFs show high catalytic performance under mild conditions, and the aperture size of the MOF plays an important role in the diffusion of substrates in CO2 fixation reactions.

Summary: The research focused on enhancing the insolubility of poly(vinyl alcohol) nanofibers through UV crosslinking and improving adsorption capability with UiO-67 metal-organic framework. By optimizing processing conditions, smooth composite nanofibers were produced with higher specific surface area and smaller pore size, potentially due to the micropores generated by incorporating UiO-67, which led to enhanced phosphate removal.

Summary: Towards a carbon-neutral future, the anthropogenic recycling of captured carbon dioxide into valuable chemicals and materials is an attractive pathway. A zeolitic imidazolate framework (ZIF-9-ImBr) with electrophilic cobalt ions and CO2-philic nitrogen-rich units was synthesized and used as a catalyst for the solvent-free synthesis of cyclic carbonates. The ZIF-9-ImBr exhibited good catalytic performance and could be easily recycled. This work highlights the potential of functional ZIF-based materials for CO2 capture and conversion.

Summary: Three different carbon nanoforms were used as supports for the direct polymerization of a bis-vinylimidazolium salt, showing that nanotube-based materials have improved catalytic activity with high TON values. These materials successfully converted CO2 into cyclic carbonate under high temperature and CO2 pressure. Interestingly, the materials exhibited increased activity upon recycling due to changes in morphology, leading to materials with higher surface areas and more accessible catalytic sites.
