The biscalix[4]arene showed remarkably enhanced inclusion ability for the N-methylpyridinium ion due to the increasing p-basicity of the benzene rings, which interact with the guest in an edge-to-face manner, in calix[4]arene skeletons.
Thiacalix[4]arenes, in which the four methylene bridges of calix[4]arenes are replaced by sulfide linkages, were selectively oxidized to sulfinyl-or sulfonylcalix[4]arene under mild conditions with control of the stoichiometry of the oxidant. Solvent extraction of the transition and alkaline earth m
