Summary: Guest clusters in confined nanospaces have great influence on molecular recognition. Researchers have found that gas-cluster rearrangement can be systematically controlled to achieve tunable sorption and separation behavior in MOFs. By studying the packing geometries of CO2 and C2H2 clusters in CUK-1 material at different temperatures, they have successfully achieved high-purity separation of C2H2 using a one-step purification process.

Summary: We report the efficient one-step separation of ethylene (C2H4) from acetylene (C2H2) and carbon dioxide (CO2) using an ultramicroporous metal-organic framework UTSA-16. UTSA-16 exhibits high uptakes for C2H2 and CO2 due to electrostatic potential matching, as well as excellent separation selectivity against C2H4. This material can efficiently separate 99.9% pure C2H4 from ternary mixtures with a high productivity of 403 L kg(-1).

Summary: The study investigates a metal-organic framework called Cu-F-pymo for the separation of CO2 from fuel gases and flue gas in the chemical energy industry. Cu-F-pymo exhibits excellent size-sieving effect, selectively capturing CO2 over CH4 and N-2. The small pore size and oxygen moieties of Cu-F-pymo enable the exclusive diffusion of CO2 and enhance its binding affinity. The material demonstrates high selectivity, adsorption capacity, and dynamic CO2 capture capacity, making it a promising candidate for practical carbon capture applications.

Summary: This study investigates the structural changes of a square lattice coordination network under high pressure. The results show that the interlayer separation of the network does not increase under high pressure, but the crystals are compressed and the adsorbed molecules are released. The changes induced by pressure are discussed in terms of structural voids, framework conformation, and molecular packing. Additionally, analysis of the electron count in the pores confirms the multistep evacuation of the adsorbed molecules and suggests the existence of intermediate phases.

Summary: In this study, a new two-dimensional square lattice coordination network, sql-(azpy)(pdia)-Ni, was reported to exhibit guest-induced switching between closed and open phases. The structural transformations were enabled by the presence of a pendant phenyldiazenyl moiety on the pdia2- ligand. Various guests were accommodated through parallel slippage of layers and interlayer expansion. The network also exhibited elastic-like properties induced by adaptive guest binding.

Summary: As the freshwater crisis looms, metal-organic frameworks (MOFs) with stepped isotherms are at the forefront of desiccant development for atmospheric water harvesting (AWH). Diffusion to the sorbent bed surface limits the AWH kinetics of seven known MOFs and the industry-standard desiccant Syloid. A quantitative model exploiting isotherm shape reveals that steady-state oscillation optimizes productivity and dense ultramicroporous MOFs with a step at low relative humidity offer superior volumetric performance.

Summary: An emerging strategy in gas storage technology is the development of physisorbents that undergo transformations in response to stimuli. This study reports two isostructural light modulated adsorbents (LMAs) that transform from non-porous to porous upon adsorption. LMA-1 exhibited multi-step adsorption while LMA-2 showed a single-step adsorption isotherm. The light responsive nature of the ligand was exploited with LMA-1 showing a maximum reduction of CO2 uptake under irradiation.

Summary: Fabricating smart humidity-responsive actuators that can convert the potential of humidity into other forms of energy is crucial in the intelligence age and energy crisis. In this study, a flexible porous organic cage that can undergo reversible structural transformation upon humidity stimulation is successfully fabricated by using a polymer (PIM-1) as a matrix. The inherent porosity of PIM-1 significantly enhances the performance of the resulting actuator. These actuators can perform bionic motions and output stable voltage-level power when coupled with a piezoelectric film.

Summary: Gas or vapor-induced phase transformations in flexible coordination networks (CNs) have the potential to outperform their rigid counterparts for separation and storage applications. Ligand modification has been used to alter the properties of these materials, but they have received less attention compared to rigid CNs. In this study, a family of Zn2+ CNs with variable flexibility was investigated, and it was found that the substituent moieties attached to a linker influenced both the structure and gas sorption properties of the networks. Some networks exhibited reversible transformation from small pore to large pore phases. The insights from this study can be applied to other classes of CNs.

Summary: Compared to rigid physisorbents, switching coordination networks offer promise for gas/vapour storage and separation due to their improved working capacity and thermal management properties. X-dmp-1-Co, a coordination network exhibiting switching enabled by transient porosity, is the parent member of a family of transiently porous coordination networks [X-dmp-1-M] (M = Co, Zn, and Cd). Each member exhibits different threshold pressures for CO2, H2O, and CH4, with tuning attributed to differences and changes in metal coordination spheres and ligand rotation.

Summary: In this study, a new N-donor carboxylate linker, β-(3,4-pyridinedicarboximido)propionate (PyImPr), was used to synthesize Cd(PyImPr)(2)via two different methods, resulting in 2D or 3D supramolecular isomers. Crystal structure analysis revealed that both isomers consist of the same carboxylate bridged rod building block (RBB), and the ethylene moiety of PyImPr enabled structural flexibility. Furthermore, analysis of the Cambridge Structural Database (CSD) provided insights into the relative frequency of RBB topologies in related ML2 coordination networks.

Summary: In this study, the selection and optimization of synthesis routes for porous metal-organic materials were compared. Mechanochemistry, slurry, and solution methods were assessed for the synthesis of a 1D chain coordination polymer, and it was found that both water slurry and water-assisted mechanochemical syntheses were successful in yielding the desired intermediate. However, the resulting products exhibited different CO2 sorption profiles depending on the synthesis methods used.
