Research on Various Structural Effects of Calix[4]arene Derivatives on Extractive Separation Behavior of Metal Ions

Abstract

Calixarenes prepared by condensation reaction of p-alkylphenols are typical macrocyclic host compounds. They exhibit specific structural effects for a certain metal ions as a guest. In this article, the specific sturactural effects of calixarene derivatives containing size-fitting effect, converging effect of functional groups, allosteric effect, and complementary effect elucidated as a comparison with the results for the corresponding monomeric derivatives are introduced.
