Metal-organic frameworks (MOFs) are ac lass of crystalline porousm aterials that have been activelyu sed for several industrial and synthetica pplications.M OFs are spatially and geometrically extrapolatedc oordination polymers with intriguing properties such as tunable porosity and dimensionality.Int erms of their catalytic efficiency,MOFs combine the easy recoverability of heterogeneous catalysts with the increased selectivity of biological catalysts. It is therefore not surprising that alot of work on optimizing MOF catalysts for organic transformationsh as been carriedo ut over the past decade. In this review,recent developments in MOF catalysis are summarized, with special attention being paid to CÀC, CÀN, and CÀOc oupling reactions. The influence of pore size, pore environment, and load on catalytic activity is described. Post-synthetics tabilization techniques and hostguest interactions in caged MOF scaffolds are detailed. Mechanistic aspects pertaining to the use of MOFs in asymmetric heterogeneousc atalysis are highlighted and categorized.

“…[1][2][3][4][5][6][7][8][9][10][11][12] The highest Brunauer-Emmett-Teller (BET) surface area of MOFs reported in literature can exceed 7000 m 2 /g, 13 which is much higher than the values of other porous materials. Due to the highsurface-area characteristic of MOF, several recent studies have utilized MOFs as electrode materials for electrochemical applications, [14][15][16][17][18][19] such as supercapacitors, fuel cells, corrosion inhibition, 20 or electrochemical energy storage and conversion.…”

In this study, a simple and effective direct inkjet printing method was developed to prepare porphyrinic metal-organic framework (MOF) thin films for electrocatalysis. First, crystals of a zirconium-based porphyrinic MOF (MOF-525) with crystal sizes ranging from 100 to 700 nm were synthesized by adjusting the content of benzoic acid in the solvothermal synthetic process. The synthesized crystals showed similar surface area of 2500 m 2 /g with a unique pore size of 1.85 nm. However, some structural defects was found in the smallest crystals of 100 nm due to the fast crystallization process. After suspended in dimethylformamide, the MOF crystal suspensions were inkjet printed to fabricate uniform MOF-525 thin film patterns. With the help of great precision in liquid deposition, thicknesses of the printed MOF-525 thin films can be accurately controlled by the number of printed layers. With smaller crystal size, the printed MOF thin films showed more compact stacking and better contact with the substrate. The printed MOF thin films were applied for electrocatalytic nitrite oxidation. The effects of both film thickness and crystal size on printed film morphology and electrocatalytic activity were investigated in details. The printed MOF nitrite sensor showed a great detection limit of 0.72 μM and a high sensitivity of 40.6 μA/mM-cm 2 . In summary, this study demonstrated the feasibility of the proposed printing process for electrochemically addressable MOF thin films and can be further applied for many other electrochemical applications.

“…However, due to their low chemical and thermal stability, these are not applicable for reactions that require severe conditions [3,7,49,50]. MOFs were used as a catalyst or catalyst supports for a diversity of organic transformations including Friedel-Crafts reactions [51][52][53][54][55], Knoevenagel condensation [56][57][58][59][60], aldol condensation [61][62][63], oxidation [64][65][66][67], coupling reactions [68][69][70][71][72][73][74][75], cyano silylation [15,76,77], carbon dioxide fixation [78,79], etc ( Fig. 1).…”

Metal-organic frameworks (MOFs) are an emerging class of porous materials created by the assembly of inorganic connectors and organic linkers. They have potential applications in fields such as gas storage as well as separation, sensing, catalysis, and drug delivery due to its properties such as flexibility, porosity, high surface area and functionality. Among the various synthetic approaches for the preparation of MOFs, solvothermal and microwave-assisted methods are of particular importance, and hence have been used frequently. They have been recently used as heterogeneous catalysts in Friedel-Crafts reactions, condensations reactions, oxidations, coupling reactions, etc. However, owing to the low thermal stability and moisture sensitivity, their catalytic applications are limited. This short review covers recent developments in the synthetic methods employed for the preparation of MOFs as well as their catalytic applications.
