Stereoselective Single Step Cyclization to Give Belt-Functionalized Pillar[6]arenes
Two macrocycles were synthesized through cyclization reactions of secondary benzylic alcohols, giving pillar[6]arenes with a methyl substituent at each belt position.

Angewandte Chemie International Edition, Volume 65, Issue 25, 15 June 2026.Geminal difunctionalization of readily available building blocks provides rapid access to molecular complexity. This work introduces a strategy for installing two distinct functional groups on a carbonyl carbon by transforming it into a donor–donor diazo compound, enabling both batch and flow applications with broad solvent compatibility.

European Journal of Inorganic Chemistry, Volume 29, Issue 16, 4 June 2026.The correlation between the structures of metal complexes immobilized in the mesopores of hydrophobically modified silicate supports was examined in relation to the catalytic activities toward C‐H oxidation. On the alkene oxidation with H2O2, the iron catalyst bearing bis(imidazolyl)methane ligand promotes allylic oxidation, whereas the mononuclear ...

Structural and Chemical Engineering of Sub‐Nanochannel Membranes Toward Ion Selectivity
Advanced Functional Materials, Volume 36, Issue 46, 8 June 2026.This review summarizes recent advances in structural and chemical engineering of sub‐nanochannels for ion selectivity. We first introduce fundamental ion transport mechanisms within sub‐nanochannels, followed by strategies to tune pore size, geometry, and surface functionalities, categorized into charge‐based, ion‐recognition, hydrophilic bonding, and ...

Intelligent Molecular Recognition in Hydrogen‐Bond‐Mediated Supramolecular Polyhedra
SmartMat, Volume 7, Issue 3, June 2026.This perspective highlights the construction of sophisticated hydrogen‐bonded supramolecular polyhedra from macrocycles by emulating the hierarchical assembly of ferritin and viral capsids, and summarizes their selective recognition of individual guest molecules as well as the synergistic encapsulation of multiple species, demonstrating their potential
