A Robust Metal‐Organic Framework With ‘Molecular Gates’ for Efficient Separation of Ethane From Ethylene

Angewandte Chemie, Volume 138, Issue 21, 18 May 2026.
By installing an amino‐based molecular gate at a specific site within a robust zinc‐adenine framework, temperature‐tunable inversion of C2H6/C2H4 selectivity is achieved, enabling single‐step on‐stream production of polymer‐grade ethylene. ABSTRACT Ethane‐selective sorbents can enable single‐step purification of ethylene but remain elusive to date.

Crystal structure and Hirshfeld-surface analysis of an etoxazole metabolite designated R13

Acta Crystallographica Section E Crystallographic Communications
The etoxazole metabolite R13, systematic name 4-(4-tert-butyl-2-ethoxyphenyl)-2-(2,6-difluorophenyl)oxazole (C21H21F2NO2), results from the oxidation of etoxazole, a chitin synthesis inhibitor belonging to the oxazoline class, widely used as an insecticide/acaricide since 1998.

Selective Sequestration of Toxic NOx Gases by P‐Doped Graphene: A Density Functional Theory Study

Advanced Physics Research, Volume 5, Issue 6, June 2026.
P‐doped graphene (P‐grap) is explored as an NOx sensor through DFT simulations. The analysis of its geometry, binding energies, electronic properties, and atom‐in‐molecule characteristics demonstrates that P‐grap is a selective sensor for NOx among a mixture of various gases.

Synthesis, X‐Ray Analysis, Anticancer Activity, Computational, and in Silico Studies of New Thiophene Pyrazole Conjugates

ChemistryOpen, Volume 15, Issue 6, June 2026.
Two new thiophene–pyrazole derivatives, 8a and 8b, were synthesized from thiophene 3 precursor and fully characterized. The structure of 8a was confirmed by single‐crystal X‐ray diffraction, which revealed a nonplanar conformation stabilized by NH···O hydrogen bonding and weak intermolecular contacts.

Revealing Distinct σ–σ Stacked Supramolecular Configurations Through Electrode Interface Engineering

Small Structures, Volume 7, Issue 6, June 2026.
This chapter investigates the electronic properties of σ–σ stacked supramolecular junctions using Au–Ge alloy electrodes in scanning tunneling microscope break‐junction (STM‐BJ) measurements. It demonstrates how the hybrid metal–semiconductor interface (Au–Ge) alters conductance compared to pure Au, revealing distinct orbital alignment and stabilized ...

Spin Crossover around Room Temperature: Effects of Remote Ligand Symmetry Breaking within Jäger‐Type Iron(II) Complexes

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 8, 25 May 2026.
Remote symmetry breaking in Jäger‐type iron(II) complexes shifts stepwise spin crossover (SCO) profiles to continuous profiles with transition temperatures around room temperature. In a bottom‐up approach, we studied the feedback of slight molecular modifications on the spin crossover (SCO) properties of otherwise structurally conserved iron(II ...
