Isodesmic Supramolecular Assembly of Phenylethynylene Bis‐Urea Macrocycles

Chemistry – A European Journal, EarlyView.
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, EarlyView.
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

Exploring Calixarene‐Based Pseudorotaxane Architectures: Threading Ammonium Axles With an Exo‐Rim π‐Functionalized Calix[6]Arene Macrocycle

Chemistry – A European Journal, EarlyView.
This research presents a novel 1,4‐π‐functionalized calix[6]arene with enhanced interactions with dialkylammonium axles. We investigate threading behavior in CDCl3, highlighting how exo‐rim π‐functionalization affects binding affinity and stereoselectivity.

Carba‐closo‐dodecaborates as Superchaotropic Anions

Chemistry – A European Journal, EarlyView.
The singly charged boron cluster anion CB11H12– forms strong inclusion complexes with cyclodextrins, interacts strongly with nonionic polymers, and serves as an effective transmembrane carrier, positioning itself as the smallest superchaotropic anion known to date. .

Morphological Transitions in the Self‐Assembly of Rigid Sphere–Rod Amphiphiles Achieved by Adjusting the Linker Length

Chemistry – A European Journal, EarlyView.
Linker length regulates the self‐assembly of rigid sphere–rod amphiphiles. Long linkers enable rigid sphere–rod molecules to undergo solvent‐dependent conformational switching between I‐ and T‐shaped states, driving morphological transitions of the assemblies from striped spherical structures to onion‐like structures.

N‐Sulfonyl Azalevoglucosan: A Versatile Platform for the Synthesis of Polysubstituted Piperidines

Chemistry – A European Journal, EarlyView.
Gain by strain: The synthesis of a levoglucosan analog, in which the pyranose oxygen has been replaced by a nitrogen, allows navigation on the piperidine ring to iteratively install functional groups at C1, C2, C3, C4, and C6 positions using simple experimental protocols with minimal protecting group manipulation.

Thermophoresis of cyclodextrins and cyclodextrin-drug-complexes

, 2017
The behaviour of biomolecules in a temperature gradient, known as thermodiffusion, changes when a ligand binds. In recent years, this effect has been used to gain detailed information on binding dynamics, although the physicochemical processes are still unclear [1].

Nanofiber PVA‐Based Membranes Incorporating Functionalized Spanish Broom Derivatives for Sustainable Water Purification

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.
