Special Issue Information

Dear Colleagues,

Since the start of the 21st century, materials based on metal–organic formulations have gained global attention due to their novel structures, properties, and broad-spectrum applications. Limitless combinations of metals with organic materials have introduced an exhaustive library of well-designed, porous coordination compounds, such as (i) 0D discrete polyhedra or (ii) 2D or 3D coordination polymers. Simple, discrete supramolecular cages, i.e., metal–organic polyhedra (MOPs) and metal–organic frameworks (MOFs), are rapidly growing due to their manageable physical and chemical properties, structural diversities, exceptional porosities, and variable environment due to adjustable functional group moieties. These coordination compounds play remarkable catalytic roles in numerous important chemical transformations, providing a path from the molecular dimensions of catalytic pathways towards well-behaved, heterogeneous catalytic systems. The merger of Lewis acidic/basic sites, hydro-philic/phobic oriented interaction, host–guest complexion (mimicking enzymatic action), and encapsulation of catalytically active gust species imparts characteristic features for these compounds’ extraordinary performance in terms of high turnover number/frequency (TON/TOF) at the nanoscale. MOFs and MOPs, as solid-state materials, combine the benefits of heterogeneous catalysis (for example easy post reaction separation, catalyst reusability, and high stability) and homogeneous catalysis (high efficiency, selectivity, tailorable design of catalytic active sites, and mild reaction conditions). The conceivable organization of metal and ligands as active reaction sites along with their chemical functionalization at the nano level demonstrates the capacity to build up MOF or MOP nanoreactors particularly tailored for catalytic challenges.

Industry is benefitted by novel catalyzed reactions and thus this significantly contributes to the global economy. Metal–organic materials-based catalysts for various organic transformations like addition, condensation, elimination, cyclization, isomerization, oxidation–reduction, and substitution, along with reactions involving energy/fuel generation and activation of small molecules (N2, O2, H2, H2O, CO2, CO, etc.) are very impressive. The role of these materials as chemical catalysts, electrocatalysts, photocatalysts, and supports for real active catalysts has been well established. Thus, more efforts are required to develop these highly selective systems to create future catalysts with stability, robustness, and reusability. This will assist the advancement of the vast field of catalysis based on metal–organic materials.

This research topic welcomes submissions in the form of original research articles, reviews, and mini-reviews on the themes of catalysis based on metal–organic materials.

Metal-organic frameworks (MOFs) are porous coordination polymers with interesting structural frameworks, properties, and a wide range of applications. A novel 3D cadmium(II)-carboxylate framework, CdMOF ([Cd2(L)(DMF)(H2O)2]n), was synthesized by the solvothermal method using a tetracarboxylic bridging linker having amide functional moieties. The CdMOF crystal structure exists in the form of a 3D layer structure. Based on the single-crystal X-ray diffraction studies, the supramolecular assembly of CdMOF is explored by Hirshfeld surface analysis. The voids and cavities analysis is performed to check the strength of the crystal packing in CdMOF. The CdMOF followed a multistage thermal degradation pattern in which the solvent molecules escaped around 200 °C and the structural framework remained stable till 230 °C. The main structural framework collapsed (>60 wt.%) into organic volatiles between 400–550 °C. The SEM morphology analyses revealed uniform wedge-shaped rectangular blocks with dimensions of 25–100 μm. The catalytic activity of CdMOF for the solvent and cocatalyst-free cycloaddition of CO2 into epichlorohydrin was successful with 100% selectivity. The current results revealed that this 3D CdMOF is more active than the previously reported CdMOFs and, more interestingly, without using a co-catalyst. The catalyst was easily recovered and reused, having the same performance. Full article
