Calixarene-based langmuir monolayers : from crystallization templates to metal organic networks [PDF]

open access: yes, 2015
Molecular self-assembly plays a pivotal role in biological processes and living organisms can be considered as the result of the self-assembly of discrete molecular building blocks into sophisticated functional structures.

Encapsulation of Linear and Cyclic Alkanes in Water Within a Dimeric Deep‐Cavity Sulfonatocalix[4]arene Capsule

open access: yesChemistry – A European Journal, EarlyView.
Captured in water. A tetrasulfonated deep‐cavity calix[4]arene encapsulates linear and cyclic alkanes, as well as benzene and hexafluorobenzene, in water by forming a self‐assembled dimeric capsule. The binding affinity is guest size‐dependent. For linear alkanes, the affinity peaks at n‐hexane, while cyclooctane is the most strongly bound cycloalkane.

Macrocyclic Arenes Functionalized with BODIPY: Rising Stars among Chemosensors and Smart Materials

open access: yesChemosensors, 2020
Macrocycles play a crucial role in supramolecular chemistry and the family of macrocyclic arenes represents one of the most important types of hosts. Among them, calixarenes, resorcinarenes and pillararenes are the most commonly encountered macrocyclic ...

Super‐Electron‐Donor Polymers: From Monomer Design to Redox Functionality

open access: yesSmall, EarlyView.
2,2'‐Bipyridinylidenes are known for their “super‐electron‐donor” properties and have therefore been used beyond the field of organic synthesis. Their two‐electron redox process at a low potential of 1.8 V vs. Li/Li+ makes them attractive negative p‐type electrode‐active materials.

Strontium (II)-Selective Potentiometric Sensor Based on Ester Derivative of 4-tert-butylcalix(8)arene in PVC Matrix

open access: yesSensors, 2004
: Membranes of 4-tert-butylcalix(8)arene-octaacetic acid octaethyl ester (I) as an electroactive material, sodium tetraphenyl borate (NaTPB) as an anion excluder, and tri-n-butyl phosphate (TBP) as a solvent mediator in poly(vinyl chloride) (PVC) matrix ...

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

open access: yesChemistry – 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

Supramolecular Organocatalysis in Water Mediated by Macrocyclic Compounds

open access: yesFrontiers in Chemistry, 2018
In the last decades many efforts have been devoted to design supramolecular organocatalysts able to work in water as the reaction medium. The use of water as solvent provides promising benefits with respect to environmental impact.

Hydroformylation of Olefins With Paraformaldehyde Catalyzed by a Rhodium(I)/Diphosphine/Diphosphoramidite System

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 34, 11 September 2026.
A new dual‐ligand rhodium catalytic system based on [RhCl(cod)]2, BINAP or BIPHEP, and a diphosphoramidite ligand enables the hydroformylation of olefins using paraformaldehyde as a syngas surrogate. The system efficiently converts vinyl arenes, alkyl olefins, cyclopentene, and allyl acetate with high activity and regioselectivity.
