Summary: Integrating covalent organic framework (COF)-metal organic framework (MOF) hybrid materials is an effective way to develop a ratiometric fluorescence method. In this study, lanthanide organic frameworks were grown on the surface of a COF, resulting in a COF-MOF with high thermal and chemical stability. The COF-MOF exhibited dual emissions and fluorescence resonance energy transfer (FRET) process from the COF to MOF, making it suitable for ratiometric fluorescence detection of phosphate.

Summary: Inspired by natural ionic channels, researchers developed an asymmetrical MOF-in-nanochannel architecture to discriminate monosaccharide enantiomers. The architecture combines oxidase-mimicking and Fenton-like catalysis in homochiral mesoporous CuMOF pockets, and the identification performance is enhanced by the increased oxidase-mimicking activity of Au nanoparticles under LSPR excitation. This study provides a promising strategy for designing an enantiomer discrimination device and offers insights into the origin of stereoselectivity in natural enzymes.

Summary: In this study, a new composite Co-Mo bimetallic sulfide supported on carbon cloth (MoS2/CoS2/CC) was prepared via a one-pot hydrothermal sulfurization strategy as an efficient electrocatalyst for boosting hydrogen production from water electrolysis. The obtained MoS2/CoS2/CC catalyst exhibited outstanding hydrogen evolution reaction (HER) ability, with a low overpotential of 69 mV at a current density of 10 mA cm(-2) in KOH solution, comparable to advanced Pt/C electrodes. Moreover, the catalytic electrode showed excellent stability in the electrolyte of 1.0 M KOH, as confirmed by XRD analysis after the catalytic reaction.

Summary: The C-H/Et-Al exchange reaction of saturated hydrocarbons and AlEt3 using zirconium catalysts produces versatile organoaluminum compounds and ethane. The grafting of commercially available Zr(OtBu)(4) on silica/alumina provides monopodal SiO-Zr(OtBu)(3) surface pre-catalyst sites that can be activated by ligand exchange with AlEt3. This selective methyl group alumination enables the C-H alumination of various hydrocarbon substrates without significant chain deconstruction. Additionally, methane can undergo selective mono-alumination under solvent-free catalytic conditions.

Summary: We report the first complete reaction energy landscape of metal-organic framework (MOF) interpenetration, specifically in the phase transformation of NU-1200 to STA-26. The thermodynamics of this phase transformation were characterized through experiments paired with density functional theory (DFT) calculations. Time-resolved in situ X-ray diffraction and the Avrami-Erofe'ev model were used to monitor phase transformation reaction profiles and extract kinetic information. The results revealed slower phase change kinetics for MOFs with stronger bonds and a mechanistic model of partial dissolution for this phase transformation.

Summary: CALF-20, a metal-organic framework, shows selective CO2 physisorption. This study reveals that CALF-20 undergoes a structure transformation when exposed to humid environments, resulting in a new polymorph. The transformation is reversible, and the original structure can be regenerated. Computational evaluation indicates that the new polymorph has a higher CO2 heat of adsorption, potentially leading to improved CO2 sorption selectivity at low partial pressures.
