“…Metal–organic frameworks (MOFs) represent a new class of crystalline materials consisting of metal-containing nodes connected by multitopic organic linkers. MOFs stand out due to their unconventional hierarchical structure, high porosity and flexibility, which turn them into prospective materials for many applications in chemistry [ 1 ], biology [ 2 ], and physics [ 3 ]. The features of the crystal structure of specific MOFs, such as structural diversity [ 4 ], the lack of an inversion center (non-centrosymmetric) [ 5 ], and high resistance to heating [ 6 ] and humidity [ 7 ], open up new perspectives for using them as active materials for nonlinear optical devices [ 8 , 9 , 10 ].…”

Polymers with embedded metal–organic frameworks (MOFs) have been of interest in research for advanced applications in gas separation, catalysis and sensing due to their high porosity and chemical selectivity. In this study, we utilize specific MOFs with high thermal stability and non-centrosymmetric crystal structures (zeolitic imidazolate framework, ZIF-8) in order to give an example of MOF–polymer composite applications in nonlinear optics. The synthesized MOF-based polymethyl methacrylate (PMMA) composite (ZIF-8–PMMA) demonstrates the possibility of the visualization of near-infrared laser beams in the research lab. The resulting ZIF-8–PMMA composite is exposed to a laser under extreme conditions and exhibits enhanced operating limits, much higher than that of the widely used inorganic materials in optics. Overall, our findings support the utilization of MOFs for synthesis of functional composites for optical application.

Metal-organic frameworks (MOFs) represent a unique platform for fabrication of nanoparticles (NPs) of diverse composition and crystallinity. The growth of NPs from constituent parts of MOFs is usually initiated by external stimuli such as temperature, light and electron irradiation. Herein, the kinetics and NP growth mechanisms remain unexplored. Here, we utilized electron irradiation to initiate the nucleation and growth of crystalline Cu NPs of tunable size from several nanometers to hundreds of nanometers inside MOF as a precursor. Simultaneously, the process of the NPs growth, captured in real time using transmission electron microscope, demonstrates the evolution of their size, shape and spatial distribution. We also analyze the NP growth by the classical kinetic theory taking into account a phase transformation. Our results contribute to crystal engineering and developing of functional MOF-based nanocomposites.

“…Olefin/paraffin separation has been thus highlighted as one of seven most important chemical materials, metal-organic frameworks (MOFs) hold particular promise for the separation of light hydrocarbons, [6][7][8][9][10][11][12][13][14][15] because of their powerful reticular chemistry that enables them more readily tuning of their pore aperture and functionality. [16][17][18][19][20][21][22] The most popular cases of C 2 H 4 /C 2 H 6 separation at present have been mostly achieved by thermodynamic driven separation. One of the effective strategies is to immobilize the metal ions (such as Cu(I) and Ag(I)) on the pores to form the selective π-complexation with ethylene, which has been well proved by porous materials.…”

separations. [1] Ethylene (C 2 H 4 ), as the most important olefins, is the mainstay of petrochemical industry, with a global annual production of exceeding 170 million tonnes per year. "Polymer-grade" specification of ethylene is required for the manufacture of polyethylene plastic. The industrial separation of ethylene from ethylene/ethane (C 2 H 4 /C 2 H 6 ) mixtures highly relies on the repeated distillation-compression cycling at the temperature as low as −160 °C. [1,2] Such heat-driven separation involving in the phase change of isolated fractions, is highly energy-and capital-intensive. Finding energy-efficient alternatives to distillation would widely lower global energy consumption, carbon emissions, and pollution. It is feasible in principle to separate C 2 H 4 /C 2 H 6 mixtures based on porous solid materials via the energy-efficient and environmentally friendly adsorption technology. In this context, development of suitable porous adsorbents for ethylene/ ethane separation is of highly commercial significance.A number of porous materials including zeolites, [3] carbon molecular sieves, [4] and alumina, [5] have been explored for the separation of ethylene and ethane. However, the limits on deliberately designing the structure of such purely inorganic materials make them hardly meet the requirement of industrial implement. As an emerging class of microporous The development of new materials for separating ethylene (C 2 H 4 ) from ethane (C 2 H 6 ) by adsorption is of great importance in the petrochemical industry, but remains very challenging owing to their close molecular sizes and physical properties. Using isoreticular chemistry in metal-organic frameworks (MOFs) enables the precise design and construction of target materials with suitable aperture sizes and functional sites for gas separations. Herein, it is described that fine-tuning of pore size and π-complexation simultaneously in microporous copper(I)-chelated MOFs can remarkably boost the C 2 H 4 /C 2 H 6 adsorption selectivity. The judicious choice of organic linkers with a different number of carboxyl groups in the UiO-66 framework not only allows the fine tuning of the pore size but also immobilizes copper(I) ions onto the framework. The tailor-made adsorbent, Cu I @UiO-66-(COOH) 2 , thus possesses the optimal pore window size and chelated Cu(I) ions to form π-complexation with C 2 H 4 molecules. It can rapidly adsorb C 2 H 4 driven by the strong π-complexation interactions, while effectively reducing C 2 H 6 uptake due to the selective size-sieving. Therefore, this material exhibits an ultrahigh C 2 H 4 /C 2 H 6 selectivity (80.8), outperforming most previously described benchmark materials. The exceptional separation performance of Cu I @UiO-66-(COOH) 2 is validated by breakthrough experiments for 50/50 v/v C 2 H 4 /C 2 H 6 mixtures under ambient conditions.
