A Coordinatively Linked Yb Metal–Organic Framework Demonstrates High Thermal Stability and Uncommon Gas‐Adsorption Selectivity

Abstract

Enge Poren für eine hohe Selektivität: Das metall‐organische Gerüst PCN‐17 mit Ytterbium als Metallkomponente, das koordinativ (durch SO42−‐Ionen) verknüpfte, doppelt durchdrungene (8,3)‐Netze enthält (siehe Bild), ist bis 480 °C stabil und adsorbiert selektiv H2 und O2 gegenüber N2 und CO.

Polymorphic Coordination Networks Responsive to CO2, Moisture, and Thermal Stimuli: Porous Cobalt(II) and Zinc(II) Fluoropyrimidinolates

“…It is worth noting the solid-gas adsorptive properties of the last system, which gives rise to an unusual ordering of the stored gas molecules related to their ultramicroporous nature. [17] Prompted by these results, in search for new porous species with increased functionality, we began to explore other metal-ligand combinations. In this paper, we present the new [{MA C H T U N G T R E N N U N G (F-pymo) 2 } n ]·2.5n H 2 O systems (M = Co, Zn), which show a number of solid-to-solid, reversible or irreversible phase changes, also involving polymorphic species.…”

A Solid‐Solution Approach to Mixed‐Metal Metal–Organic Frameworks – Detailed Characterization of Local Structures, Defects and Breathing Behaviour of Al/V Frameworks

“…The versatile synthetic avenues and seemingly infinite combinations of (anionic) organic linkers with metal cations allow the design and synthesis of highly porous materials with precise control of chemical composition, crystal structure and topology 2. In this area, the last decade has seen significant progress in the adjustment of pore metrics,2d–2g stability, [2a–2c,3] and use in catalysis4 and gas storage/separation 2a,3c,3d,5…”

Two ZnII Metal‐Organic Frameworks with Coordinatively Unsaturated Metal Sites: Structures, Adsorption, and Catalysis

“…Single-crystal X-ray diffraction studies reveal that 1 crystallizes in the monoclinic space group P2 1 /c (Table 1), and the asymmetric unit contains two TCPB 3À ligands, three Zn 2 + ions, two coordinated DEF, and three lattice DEF molecules (Figure 1 a). The Zn(1) atom links Zn (2) 6 clusters by six 3connecting TCPB 3À ligands, thus leading to a 2D (3,6)-connected net with a mesh size of 12.9 13.8 2 (atom-to-atom separation, Figure 1 b). To the best of our knowledge, such doubly connecting 2D network represents a rare net topolo-gy of the MoS 2 -H structure with the Schläfli symbol of (4 3 ·6 12 ) (4 3 ) 2 (Scheme 2).…”

“…Two porous isoreticular Zn-MOFs, [Zn 3 A C H T U N G T R E N N U N G (TCPB) 2 ·2DEF]·3DEF (1; DEF = N,N'-diethylformamide and [Zn 3 A C H T U N G T R E N N U N G (TCPB) 2 ·2H 2 O]·2 H 2 O·4DMF (2), have been constructed, of which phase 1 can be converted into phase 2 upon heating. Desolvated 2 exhibits a highly selective adsorption behavior toward H 2 /N 2 , CO 2 /N 2 , and CO 2 / CH 4 ; [6,7] moreover, it displays size-selective catalytic activity towards carbonyl cyanosilylation [8] and Henry (nitroaldol) reactions [9] .…”
