Intramolecular Hydrogen Bond Driven Conformational Selectivity of Coumarin Derivatives of Resorcin[4]arene. [PDF]

Int J Mol Sci, 2020
In this study, the synthesis and structure of 4-aminocoumarin derivatives of resorcin[4]arene were investigated. Spectroscopic analysis and quantum mechanical calculations showed that this molecule undertakes a crown-in conformation in chloroform.

Resorcin[4]arene-based multidentate phosphate ligands with superior binding affinity for nanocrystal surfaces.

Chem Commun (Camb), 2021
We designed and synthesized two resorcin[4]arene scaffolds with four phosphoric acid binding groups. The ligands effectively bind in at least a tridentate fashion.

Thioderivatives of Resorcin[4]arene and Pyrogallol[4]arene: Are thiols tolerated in the self-assembly process? [PDF]

, 2021
Three novel thiol bearing resorcin[4]arene and pyrogallol[4]arene derivatives were synthesized. Their properties were studied with regards to self-assembly, Brønsted acid catalysis, and disulfide chemistry. One new thiosubstituted macrocycle stands out

Enaminone Substituted Resorcin[4]arene-Sealing of an Upper-Rim with a Directional System of Hydrogen-Bonds. [PDF]

Int J Mol Sci, 2020
The paper presents the synthesis of an enaminone resorcin[4]arene via a thermally activated o-quinomethide. The crystal structure indicates that in the solid state all enaminone units participate in a unidirectional seam of 12 intramolecular hydrogen ...
