“…The Knoevenagel condensation yield of benzaldehyde and malononitrile reached 98.2 %a tr oom temperature after 5h ours. It should be noted that these values are comparablet oP CN-124 (99 %), [33] Cz-MOF( 99 %), [34] and PCP-1 (96 %), [35] which makes UPC-33 ac andidate fort he CÀCc oupling reaction. The aromatic aldehydes with bulky and electron-donating groups reduce the reaction rate and yield ( Table 3, entries 7a nd 8), which are not suitable for the framework cavity.…”

“…UPC-33 has the right pore size to maximize the interaction between the gas and framework, so it exerts ah igh separation selectivity for C 3 light hydrocarbons relative to CH 4 (228. 34,151.40f or C 3 H 6 /CH 4 ,C 3 H 8 /CH 4 at 273 ka nd 1bar)a nd can selectively adsorb absorb C 3 H 6 from C 2 hydrocarbons. These results indicate that UPC-33 may be ap romising candidate for fuel gas purification and light hydrocarbon separation in the near future.I na ddition, the presence of Lewis basic ÀNH 2 groups allows UPC-33 to act as ac atalyst for size and electronically selective Knoevenagel condensation reactions.…”

A barium(II) metal-organic framework (MOF) based on a predesigned amino-functionalized ligand, namely [Ba (L)(DMF)(H O)(NO ) ]⋅DMF⋅EtOH⋅2 H O (UPC-33) [H L=4,4'-((2-amino-5-carboxy-1,3-phenylene)bis(ethyne-2,1-diyl))dibenzoic acid] has been synthesized. UPC-33 is a 3-dimensional 3,18-connected network with fcu topology with a rare twelve-nuclear Ba (COO) (NO ) cluster. UPC-33 shows permanent porosity and a high adsorption heat of CO (49.92 kJ mol ), which can be used as a platform for selective adsorption of CO /CH (8.09). In addition, UPC-33 exhibits high separation selectivity for C light hydrocarbons with respect to CH (228.34, 151.40 for C H /CH , C H /CH at 273k and 1 bar), as shown by single component gas sorption and selectivity calculations. Due to the existence of -NH groups in the channels, UPC-33 can effectively catalyze Knoevenagel condensation reactions with high yield, and substrate size and electron dependency.

A concise account on the use of transition metals copper (Cu) and palladium (Pd), as their cations as well as nanoparticles exchanged/immobilized onto porous frameworks such as zeolites, metal organic frameworks (MOFs), covalent organic polymers (COPs) and hollow nanostructures, functioning as catalysts in organic synthesis is presented. This biomimetic account, "focusing on catalytic systems in confinement" within zero-dimensional microenvironments and second sphere coordination covers primarily results from our group on N-sulfonylketenimine mediated cycloaddition, hydrogenation and C-C bond forming reactions, thus providing an interesting insight into the versatility and utility of these Cu and Pd catalysts. Other significant advantages and green credentials of confinement such as stability, selectivity, reusability, promotion of multicomponent reactions, use of green solvents, atom economy, and use of ambient conditions are highlighted at appropriate places. In the final section, our views on the current achievements and the future prospects in this area are summarized.

“…MOFs, which could be designed by varying organic linkers and inorganic joints, have attracted significant attention in recent years by virtue of their permanent porosity, open crystalline structures, tunable cavities, and extraordinary surface areas. These unique and outstanding characteristics offer a great potential range of applications in separation, gas storage, magnetism, sensor, drug release, membrane technology, and catalysis [21,22,23,24]. For example, Livingston et al prepared a kind of hybrid polymer/MOF membrane by in-situ growth (ISG) of HKUST-1 within the pores of polyimide membranes.…”

Tungsten oxide (WO3) and boron oxide (B2O3) were irreversibly encapsulated into the nanocages of the Zr-based metal organic framework UiO-66, affording a hybrid material B2O3-WO3/UiO-66 by a simple microwave-assisted deposition method. The novel B2O3-WO3/UiO-66 material was systematically characterized by X-ray diffraction, Fourier transform infrared spectroscopy, N2 adsorption, ultraviolet–visible diffuse reflectance spectroscopy, scanning electron microscopy, transmission electron microscopy, X-ray phosphorescence, and Fourier transform infrared (FTIR)-CO adsorption methods. It was found that WO3 and B2O3 were highly dispersed in the nanocages of UiO-66, and the morphology and crystal structure of UiO-66 were well preserved. The B2O3 species are wrapped by WO3 species, thus increasing the polymeric degree of the WO3 species, which are mainly located in low-condensed oligomeric environments. Moreover, when compared with WO3/UiO-66, the B2O3-WO3/UiO-66 material has a little weaker acidity, which decreased by 10% upon the B2O3 introduction. The as-obtained novel material exhibits higher catalytic performance in the cyclopentene selective oxidation to glutaraldehyde than WO3/UiO-66. The high catalytic performance was attributed to a proper amount of B2O3 and WO3 with an appropriate acidity, their high dispersion, and the synergistic effects between them. In addition, these oxide species hardly leached in the reaction solution, endowing the catalyst with a good stability. The catalyst could be used for six reaction cycles without an obvious loss of catalytic activity.
