Syntheses and aggregation properties of new water-soluble calixarenes

Abstract

Eighteen water-soluble calixarenes have been synthesized and their aggregation properties in water studied. They are six anionic calixarenes (1n) having sulphonate groups on the upper rim, nine anionic calixarenes (2n) having sulphonate groups on the lower rim, and three cationic calixarenes (3n) having ammonium groups on the upper rim. On the basis of measurements of critical micelle concentrations (c.m.c.s.) by surface tension, conductance, and spectroscopic methods, it was concluded that the aggregation behaviour of these water-soluble calixarenes can be classified into three categories: (i) non-micellar calixarenes, (ii) micelle-forming calixarenes, and (iii) unimolecular micellar calixarenes. The possible structure-aggregation relationships are discussed.
