Abstract :
Calixarenes are a readily available and important class of macrocycles in supramolecular chemistry. Calixarenes have generated considerable interest due to their basket shaped structure and as useful building blocks to synthesize selective receptors for the guest species, notably alkali, alkaline earth, lanthanide and transition metal cations. In this work studied on the complexing properties of a para-sulfonato-calix [4] arene (C281424016S4) with alkali metal cations. The complexation properties of para-sulfonato- calix [4] arene were studied by Hartree Fock method. The complexes showed different properties for the different cations, depending on the cations and the position of the substituents grafted on the ligand.
