Adsorptive separation of acetylene (C2H2) from carbon dioxide (CO2) offers a promising approach to purify C2H2 with low-energy footprints. However, the development ideal adsorbents simultaneous high adsorption and selectivity remains great challenge due their very small molecular sizes physical properties. Herein, we report lithium(I)-chelation strategy for pore space partition (PSP) in microporous MOF (Li+@NOTT-101-(COOH)2) achieve uptake selectivity. The chelation model Li+ ions within framework was visually identified by single-crystal X-ray diffraction studies. immobilized were found have two functions: (1) partitioning large cages into smaller ones while maintaining surface area (2) providing specific binding sites selectively take up over CO2. resulting Li+@NOTT-101-(COOH)2 exhibits rare combination capture capacity (205 cm3 g-1) C2H2/CO2 (13) at ambient conditions, far surpassing that NOTT-101-(COOH)2 (148 g-1 3.8, respectively) most top-tier materials reported. Theoretical calculations gas-loaded SCXRD studies reveal chelated combined segmented can bind amount through unique π-complexation, accounting improved Breakthrough experiments validated its excellent actual mixtures, one highest productivities 118.9 L kg-1 (>99.5% purity) single adsorption-desorption cycle.

Selective separation of acetylene (C2H2) from carbon dioxide (CO2) and ethylene (C2H4) remains a significant challenge in the field gas separation. Non-thermally driven technology based on metal–organic frameworks (MOFs) offers an efficient environmentally friendly approach. Herein, Ni-based anionic MOF (iMOF-1A) was employed for first time. The differential recognition various molecules is enhanced by suitable pore sizes, accessible aromatic rings, cations outside framework. Experimental results demonstrate that iMOF-1A exhibits exceptional uptake ratios C2H2/CO2 (2.27) C2H2/C2H4 (1.48), which surpass those most previously reported materials. Furthermore, ideal adsorbed solution theory (IAST) selectivity calculations display promising theoretical performance, supported molecular simulations. Breakthrough experiments further validate not only effectively separates mixtures but also excellent performance humidity stability C2H2/C2H4/CO2 ternary mixtures.

Overcoming the trade-off effects between adsorption capacity, selectivity, and enthalpy of an adsorbent is very important but remains a huge challenge. Here, we report flexible metal-organic framework (FJI-H36); it can selectively adsorb Xe from Xe/Kr mixtures with high capacity low enthalpy. Structural analyses show that such excellent performances come adaptive contraction framework; pore shrinkage enhance interactions adsorbed offset some heats. For SF6/N2 mixtures, FJI-H36 also performance SF6 through contraction, resulting in both selectivity This not only provides new for purification Xe/Kr/SF6 offers potential solution to overcome trade-offs among specific adsorbent.

Abstract Misuse of antibiotics and pesticides has led to hazardous effects on human health, livestock, agriculture, aquaculture, which urges researchers find simple, rapid, efficient, cost‐effective methods for quick on‐site analysis these organic pollutants with functional materials. Herein, a 2D chemically robust MOF: IITKGP‐71 , {[Cd(MBPz)(2,6‐NDC)]·2H 2 O} n is strategically developed ease in scalability exploited as dual sensors toward the toxic antibiotic pesticide detection via luminescence quenching aqueous medium . The framework displays exceptional chemical robustness water 3 months, an open atmosphere over wide range pH solution (pH = 3–12) day. can selectively quench nitrofuran (NFZ NFT) organochlorine DCN while remaining unaffected by other interfering pesticides, respectively. An excellent trade‐off between high effectivity (high K sv ) sensitivity (low LOD) was achieved targeted analytes. easy scalability, stability, fast responsivity, multi‐responsive nature, recyclability outstanding structural stability made this viable playing crucial role safeguarding aquatic ecosystems public health from pesticides.
