Isodesmic Supramolecular Assembly of Phenylethynylene Bis‐Urea Macrocycles

Chemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.
A soluble phenylethynylene bis‐urea macrocycle assembles in polar media via an isodesmic hydrogen bonded mechanism. Spectroscopic and morphological studies reveal nanoscale aggregates with short chain length, while guest additives modulate enthalpy and polymerization, demonstrating tunable supramolecular assembly.

Prism[5]MaxQ: A Sulfated Prism[5]Arene and Its Molecular Recognition Properties Toward a Panel of Quaternary Ammonium Guests

Chemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.
We report the synthesis and characterization of a sulfated prism[5]arene host (Prism[5]MaxQ). Prism[5]MaxQ displays ultrahigh binding affinity (Ka up to 1012 M−1) toward hydrophobic (di)cations in phosphate‐buffered saline (PBS). The work positions Prism[5]MaxQ as a new member of the family of ultrahigh‐affinity hosts poised for use as a sequestrant in

Rapidly Diversifying Hydrogen‐Bonded Organic Frameworks With Permanent Porosity

Angewandte Chemie, Volume 138, Issue 36, 1 September 2026.
This article reviews diversifying hydrogen‐bonded organic frameworks (HOFs) with permanent porosity reported over the past 15 years, based on the molecular structures of their constituent tectons. Furthermore, several distinctive aspects and concepts are described, such as permanent porosity, isostructural (isoreticular) HOFs, and multicomponent mixed ...

Hierarchical Primary‐Secondary Coordination Synchronizes Ion Flux and Sulfur Redox in Solid Polymer Electrolytes

Advanced Functional Materials, Volume 36, Issue 73, 10 September 2026.
Hierarchical coordination engineering redistributes Li+ from anion‐dominated pairing toward polymer‐mediated binding. Strong primary sites promote salt dissociation, while distributed secondary sites sustain dynamic hopping pathways. This coordination landscape couples ion flux with polysulfide conversion, suppresses transport‐conversion decoupling ...
