TL;DR: A series of novel redox-active and photoactive ruthenium(II) and osmium (II) bipyridyl-, ferrocene-, and cobaltocenium-containing macrocyclic receptors with the dual capability of selectively sensing anionic guest species via electrochemical and optical methodologies have been prepared as discussed by the authors.

TL;DR: Extensive solution 1H NMR binding studies, thermodynamic investigations, and single-crystal X-ray structure determinations reveal that the nature of the halide anion template, strength of the ion-pairing between the anions and the cationic threading component, and to a lesser extent favorable second sphere pi-pi aromatic stacking interactions between the positively chargedthreading component and macrocyclic ligand, affect the efficacy of pseudorotaxane formation.

TL;DR: In this paper, an equatorial−axial arrangement of the bidentate ligand (axial isomer), in contrast with the precursors, found as the equatorial isomer in the solid and fluxional in solution, was used for the catalytic epoxidation of cyclooctene using tert-butyl hydroperoxide as oxidant.

TL;DR: The reduction potentials of the group 1 or 2 metal, ammonium, and alkylammonium complexes are significantly anodically shifted with respect to that of the free ligand and the electrochemical properties of the "acyclic" p-tert-butylcalixdiquinones 1, 4, and 8 and their complexes have been studied using cyclic and square wave voltammetric techniques.

TL;DR: In this article, the syntheses and preliminary transition metal coordination studies of a novel calix[4]arene cryptand receptor and new 1,3-bis-pyridyl-, -bipyrideyl- and -alkylthioether calix are described.
