Summary: The hydroxyl radicals ('OH) generated on the anode play a crucial role in the electrochemical oxidation (EO) of organic pollutants for water treatment. Inspired by the oxygen evolution reaction (OER), a strategy of anode selection was proposed to stabilize deeply oxidized states ( *O and *OOH) which contribute to the generation of 'OH. Through the use of MIL-101(Cr)-coated-Ti/TiO2 anodes, fast and complete removal of aniline and phenol, as well as improved energy utilization, were achieved compared to undecorated anodes. Mechanistic investigations and density functional theory (DFT) computations further supported the hypothesis and provided insights for the development of anode materials in the EO process.

Summary: Modulation of metal centers is an effective strategy for enhancing catalytic performance. Two structurally identical MOFs, MIL-101(Cr) and MIL-101(Fe), were synthesized with different metal centers. MIL-101(Cr) exhibited enhanced H2O2 yield due to the electron-donating ability of Cr. This study contributes to the rational design and optimization of MOF catalysts for catalytic reactions.

Summary: This study presents a new and simple method to encapsulate Phosphotungstic acid (PTA) into MIL-101 (Cr) cavities, resulting in PTA-MIL-101(Cr) with a higher surface area. PTA-MIL-101(Cr) shows 1.72 times the surface area of MIL-101(Cr) due to the formation of more accessible pores. The catalyst 3%Pd/PTA-MIL-101(Cr) outperforms other catalysts in CO oxidation, thanks to the high dispersion of Pd nanoparticles and the synergistic effects between Pd and PTA. The higher activity of Pd/PTA-MIL-101(Cr) is explained through various analyses, and the stabilization mechanism is also discussed.

Summary: This study demonstrated the selective and irreversible capture of SeO32- ions from water using Fe-MIL-101 MOF with free coordination sites. The material showed high uptake capacity, excellent performance in a broad pH range, and high selectivity for SeO32- ions even in the presence of competitive anions. By forming Fe-O-Se coordination bonds, Fe-MIL-101 effectively removed SeO32- ions from natural and waste water.

Summary: This study focuses on the enantioselective discrimination of racemic compounds using a new family of chiral conjugated BINOL-porous polymers (CBPPs). The CBPPs exhibit high thermal stability, a good specific surface area, and a robust framework, making them suitable for fluorescence recognition of enantiomers of terpenes and 1-phenylethylamine. The results show that the CBPPs prepared using the Sonogashira-Hagihara carbon-carbon coupling approach exhibit stronger selectivity towards one enantiomer compared to the reference BINOL-based soluble system.

Summary: In this study, we reported a convenient and transition metal-free intermolecular propargylic C-H amination of alkynes. The reaction showed high yields for terminal, silyl, and internal alkynes with a wide range of functional groups. The regioselectivity of amination was found to be influenced by substitution pattern and relatively remote heteroatomic substituents.

Summary: Lanthanide metal-organic frameworks (Ln-MOFs) can be utilized in various research fields by combining the luminescent characteristics of lanthanides and the advantages of porous materials. A water-stable and high-temperature resistant Eu-MOF with high photoluminescence quantum yield was synthesized, showing excellent selectivity and quenching sensing for Fe3+ and ofloxacin. It also demonstrated color modulation with Tb3+ and La3+ for developing white LED components, and rare reverse adsorption selectivity in a CO2/C2H2 gas mixture. The protonated carboxyl groups in the Eu-MOF provided an efficient conducting platform for proton transfer.

Summary: Herein, a novel anionic hydrogen-bonded organic framework (HOF-IPCE-1Pd) based on a new complex of palladium(ii) with meso-tetrakis(4-(phosphonatophenyl))porphyrin is reported. The framework shows high crystallinity, simple synthetic procedure, and is easily regenerated. The directed structural transformation of the framework and the absorption of ammonia and water molecules led to the formation of a more hydrolytically stable structure (HOF-IPCE-1Pd-NH3) with a proton conductivity of 1.27 x 10(-3) S cm(-1) at 85 degrees C and 85% RH, which is one of the highest among all known porphyrin-based HOFs. It is noteworthy that the reversible absorbance of water/ammonia molecules preserves the crystal structure of HOF-IPCE-1Pd-NH3.
