Summary: In this study, a pre-synthetic pore environment design strategy was utilized to create stable methyl-functionalized metal-organic frameworks (MOFs) for enhanced low pressure SO2 adsorption and separation from CO2. The key role of increasing methyl group densities at the benzenedicarboxylate linker in optimizing pore size was demonstrated for the first time. Various methods, including gas sorption isotherms, theoretical calculations, simulations, and DFT calculations, were used to validate the SO2 separation potential of methyl-functionalized MOFs.

Summary: By utilizing solvent-oriented structural self-assembly and solvent-induced single-crystal to single-crystal transformation strategies, eight structurally distinct Cd-CPs were controllably synthesized with the same linkers for the first time. The significant role of solvents in the self-assembly and transformations in CPs has been demonstrated, and rare reversible CP-based phase transition phenomena at low temperatures were observed, including the first example of a novel turn-on-off CP-based Fe3+ ion sensor.

Summary: The intriguing properties of porous coordination polymers (PCPs) have been extensively discussed and various functionalities have been achieved by synthesizing and characterizing three different coordination polymers. Gas sorption, electrical properties in dark and light, and luminescence were studied to demonstrate the multifunctionality of these structures. The measured properties of the synthesized complexes were correlated with the individual frameworks based on dicarboxylate flexibility/substitution and the size of the metal ion.

Summary: This article provides a comprehensive review of various methods for the regeneration of MOFs after capturing H2S, SO2, and NO2. Pressure and temperature swing methods can reactivate MOFs after physical adsorption of gases. Although regenerating MOFs with chemisorbed sulfurous gases poses more difficulties, reactivation strategies such as solvent and ultraviolet irradiation-based treatments can be recommended.

Summary: The development of methods for removing sulfur oxides released by fuel oils containing sulfur is important due to negative environmental and human health impacts. Hydroprocessing is commonly used, but refractory compounds like dibenzothiophene pose challenges. Two coordination polymers (CPs) were synthesized for selective adsorptive separation of refractory compounds. Characterization techniques were used and heat activation was performed before adsorption. Both CPs showed good adsorption capacities for dibenzothiophene, with physisorption as the mechanism.

Summary: The growth of porous aromatic frameworks (PAFs) on the surface of polymer brushes is achieved for the first time. The confined environment provided by the polymer brushes leads to the formation of nanosized and homogeneous spherical PAFs. The size of PAFs can be controlled by adjusting reaction time, grafting density, and concentration of 4-bromobenzene.
