Separation is an important industrial step with critical roles in the chemical, petrochemical, pharmaceutical, and nuclear industries, as well as in many other fields. Although much progress has been made, the development of better separation technologies, especially through the discovery of high-performance separation materials, continues to attract increasing interest due to concerns over factors such as efficiency, health and environmental impacts, and the cost of existing methods. Metal-organic frameworks (MOFs), a rapidly expanding family of crystalline porous materials, have shown great promise to address various separation challenges due to their well-defined pore size and unprecedented tunability in both composition and pore geometry. In the past decade, extensive research is performed on applications of MOF materials, including separation and capture of many gases and vapors, and liquid-phase separation involving both liquid mixtures and solutions. MOFs also bring new opportunities in enantioselective separation and are amenable to morphological control such as fabrication of membranes for enhanced separation outcomes. Here, some of the latest progress in the applications of MOFs for several key separation issues, with emphasis on newly synthesized MOF materials and the impact of their compositional and structural features on separation properties, are reviewed and highlighted.

“…Many of the examples used throughout this review demonstrate that the extant boundaries between material applications are becoming increasingly blurred. A prime example of this boundary-crossing is that of a thin-film SURMOF (surface-mounted metal–organic framework) used to template polymer formation with applications for drug loading, published just this year [ 107 ]. It is also evident that applications for MOFs in chemical sensing are becoming increasingly important, with this important growing niche having been ably reviewed this year by Ghosh and co-workers [ 108 ].…”

Over the past few decades, metal–organic frameworks (MOFs) have proved themselves as strong contenders in the world of porous materials, standing alongside established classes of compounds such as zeolites and activated carbons. Following extensive investigation into the porosity of these materials and their gas uptake properties, the MOF community are now branching away from these heavily researched areas, and venturing into unexplored avenues. Ranging from novel synthetic routes to post-synthetic functionalisation of frameworks, host–guest properties to sensing abilities, this review takes a sidestep away from increasingly ‘traditional’ approaches in the field, and details some of the more curious qualities of this relatively young family of materials.

“…The adsorption performance of the chiral carbon is as high as those of recently reported sparteineand cyclodextrin-based (CD-based) nanoparticles under similar examination conditions. The adsorbabilityo fl-a nd dlactic acid onto the chiral N-doped carbon were found to be 28.26 and 14.55 %, respectively.H ence, the N-dopedc hiral carbon has a1 .94-fold highera dsorbability for d-lactic acid than l-lactic acid;t his chirally sensitive adsorbability factor is equal to or higher than those of recently reported chiral nanomaterials, namely an l-3,4-dihydroxyphenylalanine( DOPA)coated metal-organic framework (1.47), [58] synthetic polymercoatedg old nanoparticles (1.68), [59] and sparteine-and CDcoatedn anoparticles (1.4-2.5). In contrast, the pyridinic and pyrrolic functions within the carbon structure have somewhat higher basicity than the acetamide groups; [55] hence,t he carbon itself can attract protons through cation-p interactions.…”

Well-known hard-template methodsf or nitrogen (N)-doped chiral carbon nanomaterials require complicated construction and removal of the template, high-temperature pyrolysis, harsh chemicalt reatments, and additional N-doping processes. If naturallyo ccurring chiral nematic chitin nanostructures [(C 8 H 13 NO 5 ) n ]i ne xoskeletons were whollyt ransformed into an N-doped carbon, this would be an efficient and sustainable methodt oo btain au seful chiral nanomaterial. Here, as imple, sacrificial-template-free, and environmentally mild method was developed to produce an N-doped chiral nematic carbonsheath nanofibril hydrogel with as urfacea rea > 300 m 2 g À1 and enantioselective properties from renewable chitin biomass. Calcium-saturated methanol physically exfoliated bulk chitin and produced ac hiral nematic nanofibril hydrogel. Hydrothermal treatment of the chiral chitin hydrogel at 190 8Cp roduced an N-doped chiralc arbon-sheath nanofibril hydrogel without N-doping.
