The performance of a newly synthesized tetramethyl ketone calyx [4]arene ionophore in ion-selective electrodes has been investigated. Optimization of the plasticized polyvinyl chloride membrane composition has produced electrodes that exhibit a Nerns

Chemical double mutant cycles have been used to measure the magnitude of edge-to-face aromatic interactions in hydrogen-bonded zipper complexes as a function of substituents on both aromatic rings. The interaction energies vary depending on the combi

The magnitudes of a range of intermolecular edge-to-face aromatic interactions are measured using chemical double mutant cycles in synthetic H-bonded molecular zipper complexes, and good correlations are obtained with the Hammett substituent constant

Hexameric calix[6]arene ester compounds have shown an ability to extract large alkali metal ions such as caesium and rubidium in phase transfer studies. A potentiometric selectivity study has been made using two ester containing hexameric calix[6]are

The performance of sodium-selective electrode based on the ligand methyl p-t-butylcalix[4]aryl acetate, one of a new series of ionophores, is described. The selectivity pattern with respect to clinically common cations is better than those of some cu

Calix[4]-, [6]-, and [8]-arenes have been converted into a series of alkyl acetates which show significant phase-transfer activity and selectivity towards alkali metal picrates; the X-ray crystal structure of two members of the series, (1b) and (2d),

Treatment of p-t-butylcalix[4]arene with bromoacetone–potassium carbonate yields a crystalline tetraketone which shows exceptionally high phase-transfer activity towards alkali metal cations in aqueous solutions; X-ray and n.m.r. analyses show that
