Özet
The binding selectivity of di- and tri-propyl ether of p-tert-butyl- calix[4]arenes (1 and 2) with alkali metal ion have been investigated and the structure and complexation energies of a simplified host with alkali metal ions also have been optimized by ab initio HF/6-31G quantum mechanics method. The binding selectivity of di- and tri-propyl ether of P-tert-butyl-calix[4]arenes (1 and 2) towards alkali cations, based on the stability constant values of the formed complexes, is in the order of Cs+ > Li+ > Na+ > Rb+ > K+ and Cs+ > Li+ > Rb+ > Na+ > K+, respectively. On the basis of the complex's enthalpy ΔHComplex, complexation efficiencies of Cs+ and Li+ are favored towards (1 and 2). The result suggests the electron-donating tendency of the hydroxyl group is effective especially on the smaller cations.
