Summary: This paper explores the use of main group elements in supramolecular chemistry, specifically in supramolecular porphyrin-based capsules. By studying the periodic trends in the p-block, the authors demonstrate how size and structural control of the capsules can be achieved. The interaction between heavier Group 15 tris(3-pyridyl) linkers and metallo-porphyrins has been investigated, revealing the influence of bond length and oxidation state on the dimensions and reactivity of the capsules.

Summary: A novel co-polymerization strategy using both BTESE and BTESM precursors was proposed to improve the gas permselectivity of BTESE-derived membranes. The membrane with a molar ratio of BTESE:BTESM = 3:7 exhibited the highest H-2/CO2 and H-2/N-2 permselectivity while maintaining relatively high H-2 permeance. This study provides insights into the preparation of co-polymerization organosilica membranes with excellent gas separation performance.

Summary: In this study, a series of CuPd catalysts were used for the electrochemical hydrogenation of furfural. The incorporation of Pd increased the surface coverage of hydrogen adsorption and optimized the adsorption pattern of furfural, leading to an improvement in the efficiency of furfural hydrogenation. Density functional theory calculations further confirmed this phenomenon. This study provides a new strategy for designing advanced catalysts for electrochemical hydrogenation of bio-derived oxygenates.

Summary: Enantioselective resolution by coordination polymers can provide a high degree of discrimination due to well-defined pores and the ability to identify and modify binding sites. The differences in enantioselective behavior between two closely-related chiral 1D coordination polymers are related to their slight structural variations, particularly the substitution of one AlaPmDI(2-) ligand with two chloride ligands. Despite being one-dimensional, both polymers exhibit small channels with intrinsic chirality.

Summary: Due to the differences between lanthanoids and tellurium atoms, low-coordinate, monomeric lanthanoid tellurolate complexes have been difficult to synthesize compared to complexes with lighter group 16 elements. In a recent study, low-coordinate, monomeric lanthanoid tellurolate complexes were successfully synthesized using hybrid organotellurolate ligands containing N-donor pendant arms. The structures of these complexes were determined using single-crystal X-ray diffraction, and their electronic structures were investigated using DFT calculations.

Summary: Molecularly Imprinted Polymers (MIPs) modified screen-printed carbon electrode (SPCE) was developed for the determination of p-aminophenol (p-AP). The MIP was prepared using p-AP as a template, chitosan as a base polymer, and glutaraldehyde and sodium tripolyphosphate as crosslinkers. The results showed that the MIP selectively accumulated analytes on the electrode surface, and MIP with glutaraldehyde as a crosslinker increased the signal.

Summary: This study investigates the host-guest chemistry between octanuclear cubic coordination cage hosts and O,O'-diisopropyl fluorophosphate (DFP), a simulant of phosphonofluoridate G-series chemical warfare agent. The results show that two coordination cages, H-PEG and H-W, can increase the lifetime of DFP in aqueous buffer solution by protecting it from hydrolysis. Crystallographic analysis reveals that DFP binds to the windows of the cage surface, with the phosphorus-fluorine bond directed into the internal cavity, enhancing the stability of DFP. Initial studies with the chemical warfare agent sarin (GB) also indicate a reduced rate of hydrolysis when bound in the H-PEG cage. These cages' ability to inhibit hydrolysis of P-F bond containing organophosphorus guests through encapsulation may have applications in forensic sample preservation and analysis.

Summary: When immobilised on an electrode surface, MOFs can effectively enhance the OER for green hydrogen synthesis. This study investigates the potential catalytic effect of a macrocyclic amine core coordinating to cobalt ions. The modified nickel foam electrode sustained a stable OER rate at low overpotential, confirming the transformation of MOF into active cobalt oxyhydroxide.

Summary: A series of mononuclear lanthanoidate complexes have been prepared and characterised, which can be used as precursors to obtain heterobimetallic complexes. Trinuclear heteroleptic complexes have also been obtained. Some compounds exhibit slow relaxation of magnetisation at low temperatures. The study shows that the structural changes from mononuclear to trinuclear lanthanoid complexes enhance their single molecule magnetic behavior.

Summary: The design of MOFs with high connectivity ligands is an important approach for enhanced stability materials and high dimensionality networks. A new class of tetra-isophthalate hyper-carboxylate ligands containing flexible, linear diamine cores has been reported. These ligands, when combined with copper(ii) paddlewheel SBUs, form MOFs with cage-type cavities that increase in size with longer diamine cores. However, the flexibility of the ligands also leads to the formation of concomitant products.

Summary: In this study, high faradaic efficiencies for furfuryl alcohol and 2-methylfuran were achieved in near-neutral conditions through the integration of single atom copper active sites and phosphorus dopants in a single catalyst. Single atom Cu sites were identified as the active centers for the reaction, leading to enhanced efficiencies by suppressing the competing hydrogen evolution reaction. Phosphorus doping facilitated furfural hydrogenation to 2-methylfuran via a sequential two-step reduction process, opening up possibilities for selective electrochemical hydrogenation under mild conditions.

Summary: Three new amine functionalised tetracarboxylate linkers with different arm lengths were synthesised, and analysis showed that the majority of the coordination polymers obtained exhibited a divergent conformation. The flexibility of the linkers allowed for rotation of attached groups, leading to the formation of both convergent and divergent conformations in the obtained coordination polymers.
