Françoise Arnaud-Neu,Geraldine Barrett,Steven J. Harris,Michael Owens,M. Anthony McKervey,Marie Jose Schwing-Weill,Pascale Schwinte +6 more
TL;DR: The complexing properties of calix[4]arenes in which carboxylic acid ligating groups have been progressively attached to the lower rim through the phenolic hydrogen atoms have been measured with alkali and alkaline-earth metal cations in methano by means of potentiometric titrations as discussed by the authors.
Journal ArticleDOI
Selective alkali-metal cation complexation by chemically modified calixarenes. Part 4. Effect of substituent variation on the Na+/K+ selectivity in the ester series and X-ray crystal structure of the trifluoroethyl ester
Françoise Arnaud-Neu,Geraldine Barrett,Suzanne Cremin,Mary Deasy,George Ferguson,Steven J. Harris,Alan J. Lough,Lourdes Guerra,M. Anthony McKervey,Marie J. Schwinghyphen,Weill,Pascale Schwinte +11 more
TL;DR: In this article, the cation complexing abilities of a series of p-tert-butylcalix[4]arenes bearing ligating ester groups in the cone conformation have been assessed by stability constant measurements in methanol and extraction studies from water into dichloromethane.
Journal ArticleDOI
Extraction and solution thermodynamics of complexation of alkali and alkaline-earth cations by calix[4]arene amides

TL;DR: In this paper, the properties of nine new calix[4]arene tetraamides towards the entire alkali cation series and strontium have been determined.
Journal ArticleDOI
Cation complexation by chemically modified calixarenes. Part 10. Thioamide derivatives of p-tert-butylcalix[4]-, [5]- and [6]-arenes with selectivity for copper, silver, cadmium and lead. X-Ray molecular structures of calix[4]arene thioamide–lead( II ) and calix[4]arene amide–copper( II ) complexes
Françoise Arnaud-Neu,Geraldine Barrett,Denis Corry,Suzanne Cremin,George Ferguson,John F. Gallagher,Stephen J. Harris,M. Anthony McKervey,Marie-José Schwing-Weill +8 more
TL;DR: The effect of chemical modification of the lower rim of the calixarene amide complex has been analyzed with respect to cation binding by thioamide proteins in this article.
Journal ArticleDOI
Cation complexation by chemically modified calixarenes. Part 7. Transport of alkali cations by p-tert-butylcalix[n]arene esters and amides
Françoise Arnaud-Neu,Stefano Fanni,Lourdes Guerra,William McGregor,Khadija Ziat,Marie-José Schwing-Weill,Geraldine Barrett,M. Anthony McKervey,Deborah Marrs,Eileen M. Seward +9 more
TL;DR: In this paper, the co-transport of alkali thiocyanates from a source to a receiving solution through a bulk liquid dichloromethane solution is facilitated by p-tert-butylcalix[n]arene esters of lower rim calixarene acetic acids.
