Linker Symmetry Lowering as a Strategy to Tune Electronic Properties in Two‐Dimensional Conductive MOFs

Chemistry – A European Journal, EarlyView.
We present a two‐dimensional conductive metal‐organic framework (2D cMOF) constructed from an organic linker with lower symmetry than those commonly used in related systems. The resulting reduction in lattice symmetry lifts band degeneracies, reshapes the electronic structure, and opens a larger band gap.

Rapid and Reusable Amino Acid–Derived MOFs for the Removal of Estrogenic Hormones From Real Water Matrices

Chemistry – A European Journal, EarlyView.
A family of amino‐acid–derived MOFs enables ultrafast (>90–95% in 30 s) simultaneous removal of four estrogenic contaminants from water under SPE conditions. A leucine‐based MOF shows excellent regenerability and robustness in real samples, with structural evidence revealing efficient hormone encapsulation.

Compositional Stages in the Thermal Activation of Metal‐Organic Frameworks in Vacuo: In Situ Spectroscopy and Computation

Chemistry – A European Journal, EarlyView.
The ultrahigh surface area intrinsic to many metal‐organic frameworks (MOFs) may only be accessed after the removal of synthesis solvent from within the pores. This study elucidates the electronic and structural changes undergone through the guest removal process within a commonly used CUS MOF.

Impact of A‐Site Sr Substitution in LaFeO3 on Syngas Selectivity During Chemical Looping Dry Reforming of Methane (CL‐DRM)

Chemistry – A European Journal, EarlyView.
Sr doping regulates oxygen exchange and methane activation in LaFeO3, suppressing nonselective CH4 cracking and coke formation during CL‐DRM. La0.7Sr0.3FeO3 provides the optimal balance, delivering ∼40% CH4 conversion, an H2/CO ratio of 2, and >95% carbon balance.
