Consequently, they were frequently used in large excess as the supporting electrolyte in studies of cation complexation in solution. The coordination chemistry of the alkali cations blos

J. Seifert,Ch. Schubert,M. Gerlachst—guest chemistry related to calixarenes have been very limited [1–3]. In fact, Gutsche stated in his 1985 review article that there are no published data in support of solution complexes of calixarenes [2]. This is in sharp contrast to cyclodextrins which can form a variety of host—guest-type solu

While most early studies concerned the chemistry of aryloxide ligands and this continues to be a focus [7–10], the prominence of aryl ether units in macrocyclic systems such as
