Summary: Modulated self-assembly protocols have been used to develop efficient, HF-free syntheses of flexible PCPs (metal-organic framework materials) MIL-53(Cr), MIL-53(Cr)-Br, and MIL-53(Cr)-NO2. These PCPs exhibit excellent SO2 uptake and high chemical stability against dry and wet SO2. Solid-state photoluminescence spectroscopy reveals that all three PCPs can effectively sense SO2, especially MIL-53(Cr)-Br, which shows a 2.7-fold decrease in emission upon exposure to SO2 at room temperature, suggesting potential sensing applications.

Summary: Three coordination compounds were synthesized and characterized from the reaction of copper(ii) bromide with the flexible bis-tetrazole organosulfur ligand, 1,2-bis(1-methyl-1H-tetrazole-5-ylthio)ethane (bmtte). Different reaction conditions led to the formation of polymeric 2 & INFIN;Cu2Br4(bmtte) (1), trinuclear [Cu3Br4(bmtte)(2)] (2), and tetranuclear [Cu2Br2(bmtte)](2) (3) compounds with different structures. The thermal stability, aqueous behavior, and reactivity of the compounds were investigated, and a new polymeric compound (8Cu4I4)-Cu-2(bmtte)(2) (4) was prepared through solid-state reaction and microwave irradiation. The redox behavior of the compounds was analyzed by cyclic voltammetry.

Summary: The nature of metal plays a key role in determining the flexibility and responsivity of isomorphous flexible metal-organic frameworks. In the case of DUT-8(M) family, different metal ions (Ni, Zn, Co, Cu) in the paddle wheel cluster result in various behaviors upon desolvation and adsorption. Ni, Co, and Zn compounds undergo a phase transition to closed pore phase and show gate opening behavior, while Cu-based compounds exhibit different flexible behavior. Desolvation of DUT-8(Cu) does not lead to the formation of closed pore phase, regardless of particle size.

Summary: In this study, chiral amine-alcohol-functionalized UiO-68-typed Zr-HMOFs 1-3 were prepared to separate amino acid derivatives with large pi-binding groups. The adsorption of Fmoc-L/D-AAs by these Zr-HMOFs exhibited quick adsorption, high adsorption capacity, and different enantioselectivity. The results showed that the matching of pi-binding groups between the confined chiral space of adsorbents and chiral adsorbates increased enantioselectivity, while redundant identical binding sites weakened enantioselectivity.

Summary: Designing porous materials that can purify and safely store C2H2 is crucial for industrial usage. We examined the metal-alkyne interaction of Pd-II and Pt-II on C2H2 sorption and separation in two isostructural NbO metal-organic frameworks (MOFs), Pd/Cu-PDA and Pt/Cu-PDA. The results showed that Pd-II undergoes a spontaneous chemical reaction with C2H2, leading to structural collapse and loss of C2H2/CO2 sorption and separation. Conversely, Pt-II forms a strong di-sigma bond with C2H2, resulting in high C2H2 capture. The reusable Pt/Cu-PDA efficiently separates C2H2 from C2H2/CO2 mixtures with satisfying selectivity and C2H2 capacity. This research provides valuable insights for designing high-performance MOFs for gas sorption and separation.

Summary: A new coordination polymer, [Cd(DMSO)(H2O)](3)[Fe(CN)(6)](2) (CdHCF-T), with a trigonal P-31c crystal structure, was synthesized in a DMSO/H2O mixed solution and underwent a single-crystal to single-crystal transformation to form a Cd Prussian Blue analogue (Cd-PBA) by replacing the coordinated DMSO molecules with H2O. This rare phenomenon in transition metal hexacyanometallates could offer a new strategy for obtaining new structures and overcoming the difficulty of growing single crystals of Prussian Blue analogues. Gas sorption and separation studies on the obtained Cd-PBA were conducted to evaluate its C2H2/CO2 separation capability.

Summary: By incorporating AuPd alloy nanoparticles into Cu2+-doped metal-organic frameworks, a direct catalytic conversion of methane to methanol can be achieved at mild temperature with H2O2 as an oxidant. The microenvironment parameter of Cu-UiO-66 not only improves the methane adsorption and activation, but also affects the generation of hydroxyl radicals in H2O2 reaction pathways, resulting in a volcano-type dependency of methanol selectivity on Cu contents. This work demonstrates the importance of modulating the microenvironment of catalytic centers in achieving direct catalytic oxidation of methane to methanol.
