Acridane[4]Arenes: Scope of the Macro-Tetramerization, Derivatization Options, and Water-Soluble Derivatives. [PDF]
Acridane[4]arenes (A4As) are introduced as a versatile, conformationally restricted macrocyclic platform accessible in six steps and good yields. Expanded lower‐rim scope, selective upper‐rim functionalization, and N‐Boc modification enable controlled self‐assembly into a dimeric cage that binds tetrabutylammonium salts.

Binding Properties and Supramolecular Polymerization of a Water-Soluble Resorcin[4]arene. [PDF]
A ditopic water-soluble resorcinarene is shown to bind salts and undergo self-inclusion to assembly into a supramolecular polymer.

Functionalized Calix[4]Nanocones. [PDF]
Herein we present a synthesis of a nanocone based on a calix[4]arene, which has additional functional groups at the peripheral rims. Due to its rigid structure in combination with alkoxy groups on both the upper and the lower rim, the nanocone was tested for the binding of alkaline ions in solution. It exhibits high selectivity for binding Na+ over Li+

Exploring the Glycosylation Reaction Inside the Resorcin[4]arene Capsule
In the past decade, there has been an increased interest in applying supramolecular capsule and cage catalysis to current challenges in synthetic organic chemistry. In this context, we recently reported the resorcin[4]arene capsule-catalyzed conversion of α-glycosyl halides into β-glycosides in high selectivity.

Light-actuated resorcin[4]arene cavitands [PDF]
Abstract A light-actuated resorcin[4]arene cavitand equipped with two quinone (Q) and two opposite Ru(II)-based photosensitizing walls was synthesized and investigated. The cavitand is capable of switching from an open to a contracted conformation upon reduction of the two Q to the corresponding SQ radical anions by intramolecular photoinduced ...

Synthesis of Self-Assembling Resorcin[4]arene Tetrasulfide Adsorbates [PDF]
The synthesis of a new type of host adsorbate possessing a large resorcin[4]arene headgroup and four di-n-decyl sulfide chains underneath is described. The cross-sectional area of the alkyl chains is equal or larger than that of the headgroups which makes these resorcin[4]arene tetrasulfides suitable for self-assembly onto gold surfaces to form well ...

Non‐Dilute Synthesis of Macrodiolides and Macrotetrolides Enabled by Confinement Catalysis
Confinement catalysis within a hexameric resorcin[4]arene capsule enables macrolactonization under non‐dilute conditions (up to 0.1 M), overcoming the limitations of high‐dilution protocols (0.1–10 mM). This strategy provides direct access to 18–32‐membered macrodiolides and 26–32‐membered macrotetrolides in one pot and unlocks previously inaccessible ...

Intelligent Molecular Recognition in Hydrogen‐Bond‐Mediated Supramolecular Polyhedra
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
